Personally, I'm inclined to answer "yes" and "Perhaps add flags like in
[[MediaWiki:TitleBlacklist]], one of which would indicate that this line
should not be prefixed with /^https?:\/\/+[a-z0-9_\-.]*/"

This sounds sensible to me.

Should have checked the bug list beforehand. This above modification would be much appreciated.

On the English Wikivoyage, we have added tel:// protocol links to phone numbers
so that users can dial through on their mobile phones. However, since tel://
links are considered external links, all new phone numbers added now require a
CAPTCHA to be filled.

I checked MediaWiki:Captcha-addurl-whitelist, but it seems that it is
restricted to HTTP/HTTPS. Is it possible to modify it to accept tel:// links,
and maybe even geo:// links?

Change 97317 had a related patch set uploaded by Anomie:
Allow 'noprotocol' option in captcha-addurl-whitelist

Thanks for the quick patch.

To confirm, the regex for whitelisting tel: links would be something along the lines of -

tel <noprotocol> ?

I had it on my todo list since November 1, and your comment coincidentally came at the same time I found the combination of volunteer time and motivation to work on it ;)

I'd use "tel:// <noprotocol>", or "tel: <noprotocol>" if the links don't use the //.
