TL;DR: Godot does support WASM project exports.

> The WASM distribution channel is a huge potential selling point for Bevy. You don't get that with Unreal, and AFAIK, with Godot either.
To clarify: if by "WASM distribution channel" you mean "exporting for the Web"--Godot has supported exporting & running projects in a web browser for around a decade[0].
(WASM has been supported since Godot 3.0[a] & is still supported in the current Godot 4.3[b][c]. Even prior to WASM, Godot 2.1 supported export for web via `asm.js`[d].)
Godot even has an editor[e]... :) which also runs in a browser via WASM[f].
That said, yes, you're correct that WASM support in both Bevy & Godot is a selling point--particularly because people often use Game Jams as an opportunity to try out new game engines and as "everybody knows" no-one[i] downloads executables from game jams so you'll get way more people trying your game[j] if they can play it in a web browser.

[e] A light-hearted tongue-in-cheek jab played for cheap laughs with my only defense being that I've used both Godot[g] (since 2018) & Bevy[h] (since 2022) for 2D/3D game jam entries of varying degrees of incompleteness; participated in both communities; and am supportive of both endeavours. :)
