Current definition is in RFC 4880:
https://tools.ietf.org/html/rfc4880#section-9.3

So a reasonable in-development implementation will obviously use the
100..110 range for a "Private/Experimental algorithm" while this is
being added to the spec instead of just picking a number.

+    COMPRESS_ALGO_ZSTD      =  4,

No wait I think you just did.
