Hey,
i’m not sure who is “right” as i’m just using ownCloud but it seems it could be possible that the repository might not tell the full truth https://github.com/owncloud/core/issues/40241#issuecomment-1693110093:
There is much more to do then these few code changes.
and i think some later comments seems to confirm that (some one not from ownCloud assumes a week of work but that might be also not valid, too much or too less).
But i think it maybe doesn’t matter as a final comment in that issue says:
No need to continue in here. PHP 8.x will come these days…
What i think still could be improved from the ownCloud people side could be the communication around such topics. If they would have clear statements on the rationale of the decisions to not support PHP8 until now if could have avoided various guessing or possible misinterpretations on the reasons
