[RFC]: Remove laminas-db from require-dev

[arhimede]

RFC

Q	A
Proposed Version(s)	2.25.0
BC Break?	Yes

Goal

Remove laminas-db from require-dev and remove the SaveHandler DbTableGateway class

Background

Currently, in composer , at the require-dev section, it's called the laminas-db package.
Also, composer allow PHP 8.4 but laminas-db does not allow it (yet).
laminas-db is in security mode, so we should not use it in new releases

Considerations

We should decide if the save handler TableGateway is a MUST
If we should remove it or replace it with something else....

Proposal(s)

Remove laminas-db from require-dev and remove the SaveHandler DbTableGateway class

Kill it with 🔥 as @Ocramius would say

We dropped the record not|exists validators in v3 of validator.

This stuff belongs in its own package and users can always copy/paste the implementation from older releases if neccesary.

[froschdesign]

We dropped the record not|exists validators in v3 of validator.

Even if I think this is right, it always raises questions.

This stuff belongs in its own package…

This path should be taken.

[Ocramius]

I'd say "drop it", and we then move it to a separate package, as @froschdesign correctly mentions.

The dependency graph needs to be slimmed down here
