Bug 14202 intends to "Break Math/texvc out of MediaWiki core into extensions" but the MediaWiki core still contains some code that used by the math extension only. i.e. ParserOptions.php and Language still contain math specific code (https://gerrit.wikimedia.org/r/#/c/87479/) https://gerrit.wikimedia.org/r/#/c/104991/ demonstrates how the caching in the math extension can be done without math specific functions.
Change 108490 had a related patch set uploaded by Tim Landscheidt: Remove math specific code from ParserOptions https://gerrit.wikimedia.org/r/108490

The removal of methods cause bug 60546, they have not been properly deprecated via the use of wfDeprecated() :(
