Does any current SegWit or blocksize increase proposal also seek an increase in the OP_RETURN byte limit? Does any current SegWit or blocksize increase proposal also seek an increase in the OP_RETURN byte limit?

Are there any current pull requests that seek an increase in the current 80 byte limit?

If the current OP_RETURN byte limit is 80, why does the StackExchange "op-return" tag still reference a 40 byte limit?

"An opcode that allows you to create an unspendable transaction output that stores up to 40 bytes of data."
Currently, there are no BIPS (Bitcoin Improvement Proposals) that seek to increase the 80 byte limit as you can see here.

Doing a cursory search on that repository, you can see that only a few mention OP_RETURN at all.
