Feature removal: ambiguous layout file search

[zachleat]

If you omit the file extension (for example layout: mylayout), Eleventy will cycle through all of the supported template formats (mylayout.*) to look for a matching layout file.

I’d like to phase out the above feature and make it not enabled by default, with the option to re-enable via config option.

This feature requires potentially 10 or 11 file system checks (one per template extension) and the ordering is ambiguous. If you have a base.liquid and base.njk—which does it select? I think for this specific case it’s better to be explicit, especially as we improve incremental builds.

this functionality will likely may be removed

Looks like you have one or two extra words there :)
