"parameters" is what the python side calls them, I think the name in
gdb is pretty concrete.
Not entirely so, but using a different name isn't without its own problems.

fwiw, and I know a lot don't like this approach,
but I personally intend to always import the gdb module with a gdb: prefix.

As you know, we also have the problem with symbol?.

A flat symbol namespace is going to have problems regardless, and I
like the prefix approach.
People don't want it to be the default though.

We're pretty much on our own though.
No one else on @gdb-patches is going to have an opinion (he boldly says :-)).
If you think gdb:parameter? vs guile's parameter? is materially
different than the current gdb:symbol? vs symbol? collision then I'm
happy to revisit and think about knobs more.

But I'd also like to hear your thoughts on the general solution of
just saying the convention is to important the gdb module with a gdb:
I think it's reasonable to assume this issue will arise again, and
who's to say guile 3.0 won't have its own knobs. :-)
