Do it, and try to somehow get around it's rough edges.
Although it has it's shortcomings, I can really recommend it, from my 
personal experience. (Which is with piano music, though.)

On the other hand: /if/ work is spent on it some time in the future, you 
might end up with scores requiring manual tweaking to convert to the new 
function. Thus, the less you rely on it doing a particular approach on 
language features inside it, the better.

Actually, neither of the two of us is working on it.
Nicolas is working hard on the new chord repetition shortcut, whose 
proper implementation in relative mode /possibly/ can give some insight 
on how to extend \parallelMusic to better work inside \relative, but 
AFAIK he did not express any particular interest in \parallelMusic.
I only made the minor modification to have it work with || instead of | 
as a voice separator (on the list, a few days ago). And Valentin 
convinced me to polish an example of how I use \parallelMusic for the 
LSR, but it's not yet in a state in which I want to set it free in the wild.

What we can expect from it in the future? Well, probably only that it 
does not become worse...
\parallelMusic is a fairly simple, but extremely useful scheme hack, as 
-Eluze wrote. It features virtually nothing but checking whether the 
voice segments have the same length, and I don't really expect this to 
change soon. For the time being, I hope you don't have \repeats all over 
the place, and I'd suggest instantiating a \parallelMusic construct for 
every volta and alternative.
