Approved, but please be more specific about which proxy API has received support for it.

Another comment on the shape; While looking at it all I had more questions which I'll try to clarify with the implementer of the feature. Let's not merge it yet.

@rebloor We settled on renaming the property. Too late for this release, so let's leave the current pathTemplate name undocumented, and document the new property (masqueTemplate) for the next release (146). For details, see https://bugzilla.mozilla.org/show_bug.cgi?id=1988988#c9

The rename happens in https://bugzilla.mozilla.org/show_bug.cgi?id=1998894
