Hmm. I think command bar and folder type features should not influence each other. EP does not switch to use "old code" systemwide, it switches on and off certain features. Maybe it is aware about folder type bug and fixes it, I do not know, but it is not because it switches all the explorer to "old code".
I can guarantee you that it really is a matter of what code is being used. The authors of Explorer Patcher (EP) and StartAllBack did not program a folder type bug fix into their products. I checked.
When you select "Windows 10 Ribbon" in EP, or "Kinda 10" mode in StartAllBack, you most definitely get the Windows 10 Explorer behavior. That is, it's the same as opening Explorer via the Control Panel. You can test this for yourself:
Select a folder that contains lots of subfolders of data (preferably with some folders containing pictures, some music, some a mix of file types, and so on. The more folders the better, but let's say a minimum of 3 levels deep with 3 folders at each level and at least 3 files per folder.
Right-click that folder (i.e. the top of the folder tree) and select Properties, Customize, select a folder type, other than General items, check the "Also apply this template to all subfolders" and then click OK (and, no, it does not matter if you click Apply before clicking OK).
Navigate your way through the subfolders and this is what you can expect to see for the different scenarios listed below:
Windows 10
Windows 11 Explorer launched via Control Panel
Windows 11 with EP set to "Windows 10 Ribbon"
Windows 11 with StartAllBack set to "Kinda 10"
Every folder will be set to whatever folder type you select, without exception, and they will stay that way.
Windows 11 22H2 or 23H2 (without any mods)
Windows 11 with EP set to "Windows 11 Command bar"
Windows 11 with StartAllBack set to "Proper 11"
If you're on a "local disk", such as C:, you will see a mix of folder types within your test folder tree. Windows automatic folder type discovery will revert most folders back to their "detected" folder type. Your selected folder type may apply to some folders, but it will be very inconsistent.
If you're on a USB drive (that does not mount as a "local disk"), you will see that all folders are stuck at type "General items".
