That's a limitation of the bunzip2 executable, not a fundamental
limitation of the algorithm itself.

I think that's true too, while bunzip2 can actually list all full
blocks. Never tried so hard, just waited for the whole file.
Question if someone would know: is there a Linux-software freely
available that *can* uncompress the existing part of bzip2 archive?

Btw, BWT is often followed by MTF, to further increase compressibility.

bunzip2 can - just stream the output to stdout and redirect to a
file....that would seem to work.
