I thought the FC-4 change was done because 5.8.6 was not binary
compatible with modules built for 5.8.2 and earlier.  Perl changed
binary module compatibility at 5.8.3.  All versions since then have
maintained binary module compatibility.  The FC-3 perl 5.8.5 had a bug
in that it included the MODULE_COMPAT_5.8.2 and earlier and could have
loaded incompatible modules.

How big is the performance boost?
