They don't need to post SD(P)s everywhere. It's already established that most systems are adequately defended by LAC wings and shoals of pods scattered all over the place. Adequately defended against all but the heaviest attacks, that is, which would presumably be capable of blowing away a squadron of SD(P)s in addition to Mycroft, a hundred thousand pods(which doesn't need Mycroft to be devastating), a thousand LACs and any forts.
You are 100% right, they don't need to be posted everywhere, they just need to be available to reinforce any system in the Empire specifically and the GA in general. Having 350 SD(P)'s allows you the flexibility to reinforce a threatened system(s), having 140 SD(P)'s allows you to protect a few systems and leave the rest to their own devices.
If one way or another the fixed defences are compromised, the RMN needs to be able to reinforce a system. How well would it work out for the SEM if suddenly 90%+ of the systems knew that no matter what they won't be reinforced by heavy units because there are so few and the once they have are committed to the important systems like Manticore.
If the fixed defences are enough and the RMN wanted to go down that route then they should not have a Home Fleet made up of SD(P)'s, they should be 100% offensive weapons.
With the new system-defense doctrine, the only thing they need SD(P)s for is offensive power. For that, they don't need enough to sit a few in every system under their flag - they just need a few concentrated nodal task forces.
What happens if the invincible fixed defences are defeated? If you don't have the firepower to protect your territory and reinforce a systems defence you don't have a nation, you have 60 systems sharing a flag. With 140 SD(P)'s spread out into nodal forces they can be defeated in detail, or they could be send to reinforce a threatened portion of the empire and lose a large portion of their SD(P)s for months on end in Transit. If you have 140 SD(P)s and split them into three, should you be forced to reinforce one area by stripping another you could tie down 2/3 of your fleet for months in the communication/travel loop alone, by the time they become available you are done.
Think of how Haven defended itself against Honor's raids. The few locations they lost were ultimately irrelevant to Haven's overall warfighting capability. They still had Haven and Bolthole and others. It might be harsh, but the truth is that kind of expendability currently applies to many of the SEM's newest members.
Difference is that the member systems knew that there was a large fleet able to reinforce them, Haven likely had 4 or more nodal forces protecting those threatened systems. They were screaming for reinforcements and the RHN was forced to do something, if the RMN left 140 SD(P)'s in their fleet they would be unable to do anything. Having 3 Nodal forces in Talbott totalling 60 SD(P)'s and the same number in Silesia with Manticore Home fleet of 60 SD(P)'s and a central reserve of 190SD(P)'s might give the people of the empire more peace of mind. Otherwise the RMN would have to strip Peters defences to Protect Paul and ultimately leave everyone exposed.
Staying modern is easier with a smaller battle fleet, lest they fall into the trap of a Vast Reserve which acts as a motivation to resist innovation.
That might become a problem if the MA keeps hidden for a few decades or centuries, otherwise the RMN and the GA likely won't face that problem.
