In some musical manuscripts I have found chord notations with fractions and bars that represent a single complex chord of the type:

Do-7/Bb

Re7+/F#

I was wondering if this is a modern norm not yet approved by musical instruction, since chords are expressed in the classical manner like:

D7(#9)(11) RE11/9+ RE eleventh ninth augmented What do you think about this?

So does it make sense to put the slash (forward slash), which indicates the bass note, above and/or below near the two chords?

When the slash is diagonal, it indicates a chord with a different bass note; when the slash is horizontal, it indicates a chord over another chord, as in the example you provided. In your example, besides the horizontal slash, there are also diagonal slashes; it is a very detailed notation, probably to achieve a very specific sound effect.

I don't think institutions have anything to do with it ...what should they approve?

Even if written with such detailed symbols, they work a bit against improvisation (too detailed), as Geppino says, it is probably a precise and (hopefully) one-off request
