Devs don't give a shit about match maps, it has been discussed a million times that it was to the competitive scene to bring it's own map list, if it wasn't the case today, you would not make a map list for this cup and you would not ban 70% of the official map list, so I really don't know why "devs" is an excuse to do not pick unofficial maps into cups, especially when you quote them as "good map selectors" if you know what I mean.
A better excuse would have been to point the fact nobody will know the map before the matches and so, nobody will have the time to learn and prepare it, but in any case adding unofficial maps into an unofficial tournament would be a bad idea, I even wonder why nobody yet (including you) created a tournament dedicated to custom maps only, or, I don't know, a themed tournament with only snowy maps because it's christmas (sorry aus), or a springboard tournament with only new custom maps to make a strees test and find new good match maps. There are so many things to do, and we still do the same tournaments again and again.
And if you really dislike unofficial maps, you can still create a themed and/or original tournament with the current 36 official maps.
EDIT: I'm not saying that to force you to put "my" (also Undead) map into your cup, I'm just pointing a general statement I saw in this thread about it.
