Describe the feature you have in mind.

Currently, the chipped mod's variants of brazier compatible blocks do not work with the brazier. Is it possible to use a regex of some sort to add compatibility, or maybe just hardcoding compatibility for mods?

Does this solve a particular problem?

No response

Should be entire possible using block tags (adding it to brazier:brazier_base_blocks).
You can try it out using a datapack, but I can definitely also add them as optional entries to the mod itself

Datapacks are the best and most versatile way to modify these kind of things, especially block tags.
It's easier than you probably think, I recommend you give it a try
