We had a discussion about automating the call to

putting it in registerMethods. It might work. I'll look into

Ali had suggested something similar[1]. I think your concern
was that it would get called multiple times, but shared static
module constructors runs once a program (static module
constructor runs once per thread).

Ah yes...So the problem is that registerMethods emits static
ctors that fill data structures representing the methods and
the specializations. They have to run - all of them - before
updateMethods. Thus, sadly Q's suggestion won't work.
Yes I remember now...even if we arrange to put the call to
updateMethods in its own static ctor, coming after all the other
static ctors, we don't know if there will be more modules with
more methods afterwards. So we would have to do the updateMethods
work each time, lest this module is the last. And updateMethods
is costly: not only does it figure out all the dispatch tables,
it also calculates a perfect hash (if @mptr is used) using a
random algorithm.
