Not necessarily.
After feature was given publicly documented opcode it's very hard to
remove it.

Even if this reason did not exist, the marketing reason for having
this instruction still exists, so why should they remove it?

Naturally, I don't know if this particular feature got publicly
documented opcode and don't know where too look.

These instructions have public opcodes, and I gave an URL and page
number in <2024May29.085955@mips.complang.tuwien.ac.at>.
