I don't know if this is due to performance reasons, but if you supply a special page argument to #ifexist, it always returns false.

Wikitext to reproduce:

{{#ifexist:Main Page|All is usual.|ROGUE ADMIN! WOOP! WOOP! WOOP}}<br>
{{#ifexist:Special:Allpages|Nothing to see here.|BUG ALERT! WOOP! WOOP! WOOP!}}

Expected:

All is usual.
Nothing to see here.

Actual:

All is usual.
BUG ALERT! WOOP! WOOP! WOOP!

See [[testwiki:User:MER-C/Sandbox]] for the actual results.
