Discussion: Should `MOI.set` perform complex operations?

As far as I understand `MOI.set` is primarily used for setting attributes.

However, https://github.com/jump-dev/DiffOpt.jl/pull/356 introduced:
`function MOI.set(model::Model, ::DiffOpt.ForwardDifferentiate)`
as a replacement to
`function forward_differentiate!(model)`

Historically, performing more complex operations has been left (mostly?) for special functions such as:
- `compute_conflict!`
- `write_to_file`
- `read_from_file`
- `submit`
- `transform`

A partial counter argument is:
- `Utilities.PenaltyRelaxation`, but it is a `modify` not even a `set`
I do think modify here makes sense.

Are there any other arguments to each side? any other precedent?

I would like to have the reasoning for that clarified.

What are de advantages and disadvantages?

Bonus:
As a follow-up, we should have good practices and standards documented to help developers consistently make decisions in these cases.
