Default TLE Two digit years

Are there any revisions to the NORAD TLE format planned? At the moment it
uses two digit year dates. This will stop being viable around the 2060s,
when it's feasible that some satellites launched in the 1960s might still
be in orbit. Is there currently anything built into the TLE format that can
handle this? Or is everyone putting that off for now? I'm just doing some
research for a book I might write oneday, and figured it was a potential
problem of the future. Thanks,

David

Very cool. A lot of work must have went into that one. Thanks,
