Requirement for .html on Custom Page URLs

I'm curious why the ".html" is strictly required on all FTH club website pages, and more importantly, if there is any way to make it work like most other sites today where this is no longer the case. Many times we've had members/guests not find a certain page (especially an unlisted one) because they didn't realize they actually needed to append with the file type. Is this something the fine folks at FTH can address?

sorry no.
