[Dev] Removal of unblacklisted packages from [libre]?

[bill-auger]

there is no explicit procedure for removing an entry from the 
blacklist; but there is a procedure fora adding one

https://git.parabola.nu/blacklist.git/tree/README#n33

the procedure for removing one, would be simply un-doing what
was done to add it; including removing the libre replacement
package and updating the original corresponding bug report
