I cannot imagine that the wish to "remove" an existing feature is really thought!
Even no one talks about its offered usage.
Times ago someone has invented such feature and the necessary data (fields, tables, index) for it and the way thru this data and showing it - if someone wants to use this offer.
- removing the possibility of this (reading) way and
- the necessary storage of useful (log) data.
Both is a very hard cut into db-design , functionality and user-driven thinking.
Never change a running system without really live-savings needs.
Like my old boss from the seventies - who sometimes said - the users are so non-data driven and have no idea what some issues costs, WE have to think "what is good for them"…and we do not need to ask them.
It seems to me you make the same big mistake.
You cannot offer pay-accounts and than change the offered features, only because you think they are not useful or needed or wanted or well know or…or
