[PRQ#51674] Deletion Request for sdf3

MarsSeed [1] filed a deletion request for sdf3 [2]: Broken, discontinued tool, last released in 2014. Cannot be built (FTBFS). No AUR votes. Only I commented a year ago. Adopting the package to signal that I vouch for the deletion request, and I have done my due diligence in testing the viability of this build, which resulted in failure.
