I think the issue is that with frames, you want to have two paragraphs 
with the same type of environment directly after each other. In that 
case LyX just combines the paragraphs into one environment. Not only 
with frames but any environment.

That is where I suggests things could be done differently. Instead of 
continuing the same environment, LyX should just start a new one.

However, there are cases where it might seem more natural to combine 
consecutive paragraphs into one environment. One rather clear example 
are lists because new items cannot be created via an indented standard 
paragraph.

I am not sure about Quote, Verse, etc. One would have to think more 
about further distinctions.
