#Holos currently limits posts to 4 media attachments, 4 poll options, and disallows polls with media to match Mastodon's UI. However, these restrictions don't exist in ActivityPub itself. We'll be removing these artificial limits soon. Other servers (Pleroma, Akkoma, Misskey) already support more media, more poll options, and polls with attachments. There's no technical reason to restrict what the protocol explicitly allows.
