By backward compatibility do you mean allowing a layer to use one of the
offending variables? if so, what is the point?

You mean like in a script?

You mean this LF project? https://inclusivenaming.org ( Think its overly

or OE/YP folks getting involved?

If the master branch gets renamed, what about yocto-buildhistory,
yocto-buildstats and yocto-testresults? Would master branches or tags
get renamed as well? Is this part of the day's worth of work you mentioned?

Would the Yocto Project enforce a renaming in all the repos they host?

What about layer-index?
