A few release cycles back, Swiss Maps became popular (i think, particular thanks to CockroachDB) as a replacement for standard Go map[K]V.

Later, Go's stdlib map implementation was updated to use Swiss Maps internally and everyone benefited.

Do you think the xsync.Map could be considered for upstreaming? Especially if it outperforms sync.Map at all the same use cases.

There are multiple GH issues around better sync.Map. Among other alternatives, xsync.Map is also mentioned. But Golang core team doesn't seem interested in sync.Map (or a generic variant of it) improvements.
