There have been recently ranked maps that break the minimum spinner recovery time guidelines in low diffs for no apparent reason and this affects the playability of these maps negatively because beginner players have to react faster after a spinner which can cause a lot of discomfort.
Some examples I can think of (take the BPM into account):

There are also several others which I don't remember right now
Nobody pointed this issue out in the modding pages of these maps (except for the third example but it got still ranked and it has the same problem in the Advanced diff) which is quite concerning because I think this is a guideline that shouldn't be broken without a valid reason, but apparently guidelines are considered less important than rules and that it doesn't matter if you break them. Moving the following guidelines to the rules would hopefully prevent maps from getting ranked with insufficient spinner recovery time.
I would also like to add an exception for multiple consecutive spinners because those don't require time to prepare as you just continue spinning and it's already acceptable to ignore the guideline in that case.
Additionally, I also think that the guidelines regarding spinner duration should be moved to the rules as well because it is equally important to spinner recovery time in terms of playability since spinning can be difficult for new players, especially if they have very little time to react.

Spinner recovery time must be at least 4 beats unless the next object is a spinner. This is to ensure adequate time to click a hit object following a spinner.

Spinners must not be shorter than 4 beats. Players need time to recognize that they have to begin spinning.
