Preparing for DecaLog 5 / PSR-3 version

[Pierre-Lannoy]

Dear all,

Since its first release, DecaLog has been based on PSR-3 version 1, which brings with it several constraints. In particular, DecaLog is partially or totally incompatible with plugins that use version 3, making it virtually impossible to adhere to the OpenTelemetry de-facto standard and making WordPress development with frameworks such as Bedrock very “touchy“.
What's more, using it with composer or WordPress Packagist can become a real challenge in dealing with conflicting dependencies.

That's why I want to make version 5 of DecaLog a 100% PSR-3 v3 compatible plugin.

My first idea was to make DecaLog compatible with these two “major” versions of PSR-3. This feature, a first part of which is present in DecaLog 4, works well for several scenarios. But many other cases are not yet covered. What's more, not all use-cases can ever be fully covered.

This discussion is therefore open here, to enable you to provide feedback on particular plugins that are not (yet) compatible. And so that I can keep an up-to-date list, with a status…
