Leaving aside the new collada exporter.. but talking more about exporting
for game engines in general

I think that the collada spec may be ambiguous, but if blender developers
and other game engine developers (ue4 and godot for example) work together,
a more consistent spec can be made of it, maybe we could get to a open
source official importer-exporter (like ogg opus, xiph made the open
standard, the encoder and decoder are open source and maintained by them,
so people are not interested in making their own encoder-decoder, but in
getting the official one better).

If collada is a hard beast to deal with, it may be a better idea to create
a new more strict spec, maybe based in collada (or maybe not, if collada is
a bad example to follow, i dont know), collaborating with game engine
developers, and creating and maintaining an open importer-exporter that
blender and game engines implement and contribute to... also, with a common
official imp/exporter, the community would have something to test against
when creating new importers/exporters (like in other languages) and it
would be easier to achieve compatibility...

Epic has announced his interest in making indie games easier to make with
UE, and I feel they would be very receptive to talk about this and get the
team to work in this with blender developers, and i'm pretty sure that many
other game engine developers would be pleased to collaborate too.

Sorry for my bad english if you see any mistakes ;)
