I highly doubt it, the team does not have resources to do something
like that. This is the WebKitGTK dependencies policy:

   https://docs.webkit.org/Ports/WebKitGTK%20and%20WPE%20WebKit/DependenciesPolicy.html

Bear in mind that supporting older distros means refraining from using
newer versions of the libraries and build dependencies that Webkit
uses. This is already complicated, but there's a bigger problem than
that: it also means not using recent versions of the C++ language,
something that affects the WebKit project as a whole and that would
need to be agreed with Apple.

So I think making it EOL is the only viable choice at this point.
