I’d like to be able to insert
<meta protocol="web+ganarchy" default="https://ganarchy.autistic.space/?url=%s" /> into my website so that all my web+ganarchy links get handled by my own website if the user hasn’t setup their own protocol handler for web+ganarchy links.
Note that it specifically doesn’t include a name. This isn’t registering (or attempting to register) a protocol handler, it’s just a fallback.
I run https://ganarchy.autistic.space/, so this would be very useful for me.
