In point of fact, the following entry from NEWS makes this even more
doable:
** font-lock can manage arbitrary text-properties beside `face'.
*** the FACENAME returned in font-lock-keywords can be a list
of the form (face FACE PROP1 VAL1 PROP@ VAL2 ...) so you can set
other properties than `face'.
*** font-lock-extra-managed-props can be set to make sure those extra
properties are automatically cleaned up by font-lock.
