It’s not really a case of just unlocking it for other controller types. The problem is that the tool table is a firmware functionality, that specifically needs to be compiled into grblHAL. The entire component is based around the grblHAL tool table implementation, so fundamentally is not compatible with other firmwares.
I’m not sure how much sense it would make to allow it to be used on other firmwares since the only functionality that would be relevant is nicknames - every other portion of the table would be irrelevant since the information is simply not there via the firmware.
If we were to explore this, it’d need to be as an entirely new functionality. And to be honest, if we were doing that I think I’d rather explore parsing line comments as tool identifiers/tool ids from the file over adding just a nickname functionality for non-grblHAL firmwares.
