Agreed. What needs to happen is that someone (probably you) needs to paste
the new identities and declarations into a copy of vect.mac, and
someone (again probably you) needs to make up a list of test cases
to verify that the new stuff works as intended and doesn't cause problems
for the existing stuff. Maxima test cases are just pairs of expressions,
the second one is the expected result from evaluating the first one.
You're certainly not obligated in any way to work on this stuff.
It's just that it's much more likely to happen, sooner rather than later,
if you help us with it. I think it's a good idea so I might do it too,
although it probably wouldn't happen very soon.

Agreed, this should work. I've filed a bug report (# 1556765) about it.
best,
