I disagree. But it's not incompatible as long as you don't make the
:test option to make-hash-table obligatory. ;-)

Not quite. The data field in XEmacs is a plist, and the construct
above signals an error.
#s(hash-table size 2 test equal data (k1 v1 k2 v2))

XEmacs allows wrong sizes. I think this makes sense, but it probably
isn't deliberate (the structure-reading mechanism validates field
values one at a time; I don't see a provision for cross-field
consistency checks).
#s(hash-table size 10 data (y y-value x x-value))
#<hash-table size 2/29 data (y y-value x x-value) 0x587cb2e2>
