Yes but Runey's or anyone else's standards are likely different from yours or mine. There are always more bugs and issues and it is impossible to fix all of them in any game. It just depends what threshold someone has for what they are proud of and consider worthwhile.
Even Runeys released versions have had bugs, but finding bugs is only one of the reasons for beta's.
How events are added and play out are just one other reason for beta's.
It's impossible to catch all of the bugs during beta testing, but most of the worst ones would be caught, and issues with how events play out would be better.
Changes to events is one of the issues that I mentioned before that can potentially break save files.
And since Runey has been redoing some of the older events, keeping the beta's out of the general publics hands is a safeguard against people breaking their saves, playing a version that they were never meant to have.
The people with access to the beta's on Patreon all know the risks and how to avoid problems.
And as stated by someone else, posting beta's here of Harem Hotel would be a huge problem for the F95 staff, because it is almost 12 gb's in size now.
So, F95 does not want to upload and add the beta's to the OP.
