Especially if you're an #indieWeb supporter, you should consider this feature *essential*, as it's what gives you the ability e.g. to make your #RSS feeds nicely formatted even on browsers that have removed built-in support for them (i.e. basically anything except for #VivaldiBrowser).
Of course, it can be used for more than that. I wrote about this (in Italian) on my website a couple of years ago
(Fun fact: had #ActivityPub been designed around an #XML representation of linked data instead of #JSON, most of the #Fediverse could be presented on the web via #XSLT, without requiring #JavaScript, directly from the source objects.)
If you have a fediverse account, you can quote this note from your own instance. Search https://sociale.network/users/oblomov/statuses/114971053369033069 on your instance and quote it. (Note that quoting is not supported in Mastodon.)
