I was involved with a project to decomission a low code on premise platform (Sharepoint 2013). What we found was there was a lot of user enthusiasm to create stuff but when the platform was end of life and had to be decomissioned the users enthusiasm melted away.

The "IT" dept had to spend a fortune re-validating the user requirements for the various applications, documenting and then converting them into a new platform. Obviously a lot of feature creep and previously accepted bugs (no longer accepted now that responsibility was no longer theirs).

A lot of the applications were frankenstein efforts from people over the years - lots of dead code no longer used, no docs etc. As others have mentioned people create mission critical stuff for their project or team, and then leave or be away on extended leave and it breaks etc.
