Comment (by pbruin):
In the current branch, there is a new `Map._category_for` attribute that
is always a strong reference. I later thought that instead of this, it
might be better to treat `category_for` in an analogous way to `domain`,
i.e. to make it an attribute that can be either a `ConstantFunction` or to
a `weakref`. I'm undecided for the moment, so I'm keeping the original
branch in the ticket description.
The alternative branch (including #16401 and #16402) is
`u/pbruin/15618-convert_map_category`
