My experience with shared hosting on cPanel is that the CMS installations are handled by either Softaculous or Installatron. Is that the case with you @karthost ? (by the way… welcome to the forums and thanks for contributing).
If so, both of these have also said “we’ll keep an eye on the situation” - in other words they are holding off. I suspect it will only be constant pressure from both users and hosting companies that will make them move.
