I would agree however, there are many games that do VERY well promoted as GIFs on Twitter/Discord and help generate wishlists/sales/visibility.
just perusing through twitter...something like this scene would be nice to have gif export, especially if all the art/animation is made in the game already.

Again, GIF is dead - that tweet actually shows an MP4 video. Services like Twitter add to the confusion by displaying an MP4 video, and sticking a "GIF" label on it. The actual .gif file format is no longer actually used on Twitter. Nowadays "GIF" has come to mean "short, silent, looping animations", which are now generally done by videos; it does not generally refer to the actual .gif file format any more.
So if you want an animation like that, in a future Construct Animate update you'll be able to export an MP4 video and upload that to Twitter. Even if Construct did export actual .gif files, the first thing Twitter would do when you upload it is convert it to MP4, so you may as well cut out the slow inefficient format in the middle.
I have a feeling I'll be explaining this a lot over the next couple of years...
