With all due respect, your opinion here should not be what is driving
progress. If *you* don't like roll-up captions, don't use them. Others do
and want this ability. Christian (for example) found it "...very
readable...", so just because you don't like it is immaterial to this

Again, this appears to be your opinion, but can you point us to a
definitive source for this assertion?  We are not going for "effect" here,
but rather functionality, and in some instances the need (or desire) to
have rollup captions exist.  You asked for a use-case, and one was given.
That you don't like it is no cause for it to be discarded.
