Quest users can still stream from PC, but if it’s APK only, then only Android headsets can access it - even if they are in the majority. BTW you can also play WebXR from the Quest (albeit with worse performance). Most people interested in the jam will probably have the know how of their headsets though.
Depends if you are talking about the general audience or only the judges, which will be the other entrants to the jam.
For reference my download stats for last year's entry are currently:
RunawayRails_Android-Phone-Tablet.apk 24 (flatscreen only phone version)
RunawayRails_MetaQuest.apk 22
RunawayRails_Pico.apk 13
runawayrails_linux.zip 28
runawayrails_windows.zip 34
I didn't make a webxr version, godot's webxr is broken on pico.
