Wish: documentation for given up WIP-commands / command cemetery

Please - is there some way to document commands that get lost during development ?

for example i can not find _mesh2

and i can also not find

I totally understand, that commands are tested and disappear - and i appreciate that we can take part in the development process.

But can we please have a “command cemetery” - maybe the command stay as a simple command-line-message ?
typing _mesh2 will maybe result in a commandline - info
… sorry no longer maintained, check quadReMesh instead …

And maybe this info can also be set somewhere in the thread / forum / post.

Thanks…best tom
