This sometimes does work out in a more straightforward manner... I asked Cerberus for an FTTPoD desk survey in May 2020. It came back a week later as 'unable to quote... FTTP is already planned for this location'.
The exchange appeared in the Openreach build programme document a few months later, and was completed around August 2021.
Anyway, good result here. You'll probably find an altnet is hot on Openreach's heels - that was what happened to me. Waiting for FTTP in some places is like waiting for a bus... two turn up at once.
