WebM is just a container format, though it's usually used with VP9 and opus, and is functionally equivalent to using any other kind of actual video.
Animated GIFs remain quite useful for non-video animations where you don't want lossy compression, and want to use other GIF features like transparency. Animated PNGs are a potential replacement, and support all of the features of GIFs along with 24-bit color, but software support remains lackluster.

Note that Github does support the slightly better animated WebP... as long as you change the file extension to .gif :)

The extension trick works in all sorts of place. And in reverse too. You can often upload an animated GIF to sites that don't support it by just changing the extension to .jpg or .png.
I usually only need GIFs for GitHub readmes. GitHub doesn't support WebM autoplay videos.
In texting, Telegram has introduced WebM stickers so there's at least a choice there.
