Forge maps not compatible with objective gametypes

Why is it that most seemingly “official” forge maps (Guardian, Vallhalla, Zanzibar, and Lockout) are not compatible with lots of objective gametypes?

Zanzibar had no flag placements or bomb placements.
Guardian and lockout cannot play oddball because no bomb placements.
I cannot seem to find a 1 flag CTF in the database to play on any map (mostly Zanzibar or Lockout). I guess I could learn how to make my own gametypes and just put on my own objective placements, but I figured someone has had to have remade the classic maps to do something other than slayer.

Objectives must be placed by the Forger, and additional balancing is needed for consistency in matches. 1-flag doesn’t exist, but workarounds do that allow for it; check reddit halo or forgelabs’ youtube for that turorial.

Most people forge for a particular game type.
Nobody wants to take time to place other objectives.

I do though, I place flags on bomb maps, hidden stronghold terminals, mode specific spawns sometimes.

I just want the classic maps that were remade in forge to work with the gametypes they originally worked with. A forger that neglects that is not a forger.
