Motivated by these PRs:

https://github.com/StarArawn/bevy_ecs_tilemap/pull/530 Seems to fixes a real issue, but would need some work before merging (imo). https://github.com/StarArawn/bevy_ecs_tilemap/pull/525 Pretty sure that I looked at this once and it may have been fixing a real issue https://github.com/StarArawn/bevy_ecs_tilemap/pull/501 Seems to possibly do something useful, but needs work. Linked issue was vetoed, though. https://github.com/StarArawn/bevy_ecs_tilemap/pull/429 Adds support for tsx format, vetoed. https://github.com/StarArawn/bevy_ecs_tilemap/pull/405 Adds support for particular tile layouts, abandoned

Opening this so we can decide on the record what we want to do with these things and take appropriate actions in the linked PRs and not leave them in limbo forever. I am personally fine with removing them or instituting a "feature freeze" policy, with a slight preference for removing them.
