It’s a great info, Jonas. Thank you.
I didn’t know FPC has -M option for $modeswitch. Based on the official
document¹, the -M option is to select language modes, not language features.
I know changing language mode would reset mode switches. It’s no problem for me
because I wrote the code and I stick to ObjFPC mode for all the code, no
exception. But I want to use advanced record feature as well. By setting the
language mode and language features in the global config, I don’t need to write
them in every single file.

Setting a different mode resets all modeswitches to the default for that
mode (since that's one of the main points of a mode). Setting a
different modeswitch does not reset anything.
