ESPHome as standalone Docker client /data mount point

This question is about the breaking changes from esphome#5374 from @jesserockz that this is only for the add-on. What I want to do is also get my .esphome directory in a separate mount point that runs on a different PC inside docker. Maybe add another option -v /home/user/esphome-data:/data and if the /data mount point is not specified then use the old rule as .esphome under esphome.
Thanks Henry

Why? There is no info you need to play with in .esphome.

@nickrout The same reason it is moved for add on. If I only backup esphome and not .esphome my backups can be smaller and then no need to do the exclusions in backup scripts. My .esphome is about 1.8G in size.
