First, the most important part. What the heck is an intensive purpose? The saying is "For all
intents and purposes." Intensive purposes is right up there with chester drawers (chest of drawers) as things that rustle my jimmies.
Then, on to the rest of your post.

For am 8Mton ship to hit 0.3c say from a parking orbit:
try 500g to start with obtains v=at
t= v/a = 300,000,000/500*10 = 60k s = 1000 minutes = you are joking.
500g, 60,000s, = distance traveled of 9 BILLION km.
Hyperlimits are expressed in couple hundred Million. For all intensive purposes not even a military hyper capable ship will even sniff 0.3c, let alone a freighter with a military drive.
I think the "breach" 0.3c into hyper limit can be put to bed, tucked in, and left to sleep for the foreseable HV future.
I think the last time the .3c limit was important was more recent than "never." Back in the pre impeller days it was important, as hydrogen catcher fields don't work in hyper, and they wanted to bring a much velocity across the wall as possible.
More recently, I could think of a few times when it could be important. A raiding force, emerging from hyper, and carrying some velocity down with them, then cutting a cord across the system, not actually stopping, and jumping back up when they come out the other side. It could become a real issue if the system they were raiding had a stronger mobile defense force than the raiders could handle, and they had to run away.
Do I think that it will be important commonly? No.
Would it be worth it to upsize the generators just to get to a higher limit? Again no.
Is it something that needs to be kept in mind? Most definitely.
