Consider merging with multiple_selects

Problem/Motivation

From the project's page summary, it looks like many_selects was written primarily to have a D8 version of multiple_selects. Given multiple_selects already provides a D8/D9 versions, I suggest the maintainer(s) to deprecate many_selects in favor of multiple_selects and join forces in maintaining the other module.

Proposed resolution

Post issue in multiple_selects' queue, to discuss merging. Ideally, including discussion of a migration path.
