I expect that to be a hard sell? And I see no clear way to select
non-standard library names like "hello.a".

Or add a new primary

        lib_PORTLIBS = hello


        lib_ARCHIVES = hello

because the & sign is just plain ugly. Or if a new primary
is too "expensive", or if a GOOD primary name can't be found
(I'm not too fond of the above), perhaps

        lib_LIBRARIES = lib(hello)

which seems very unlikely even for a non-standard library name.

But I don't really care all that much about the exact syntax.

Yes, because I don't want this to be Automake-NG only. But since
this scheme is opt-in, the compile script "must" be adjusted to
handle libhello.a anyway. And with an adjusted compile script, I
suppose the acceptable level of ugliness elsewhere is lowered, as
it only fixes the (mostly) cosmetic naming problem.
