Rename `Monolog\DateTimeImmutable` to something else, e.g. `JsonSerializableDateTimeImmutable`

First of all, thanks for this amazing package 💙

So this is something that I'm bothered by for a long time. Every time I want to import DateTimeImmutable, PHPStorm asks me which one I want to import:

Even though the version of Monolog is namespaced, it's still annoying to think which one to pick.

I want to propose the following:

• Rename Monolog\DateTimeImmutable to something different, for example: Monolog\JsonSerializableDateTimeImmutable
• Keep the old Monolog\DateTimeImmutable as an alias for Monolog\JsonSerializableDateTimeImmutable, and mark it as deprecated.
• In the next major, remove Monolog\DateTimeImmutable

Or if there is a better way to do this, I'm all ears. I would be happy to create the PR.

Yeah i wonder if marking it internal would help? Can you try that locally maybe? There's a minor use case of passing it directly to addRecord but i dont think many people do that..

Renaming would be cleaner but a longer term solution.

Not sure what else is possible.

Marking it as internal won't do anything for PHPStorm.

And did you try if an alias helps? Because I'm guessing it would also still suggest the alias, if so that'd only be fixed in 4.0

[ruudk]

The alias won't hide it :(

So it will be a long time before I can enjoy it, but I still think it's good to prepare this for 4.0, so I created the PR:
