License clarification - SPDX identifiers for FormsReplicator

[jozefizso]

Hi! I’d like to ask for clarification about the license statement in the FormsReplicator project, specifically the SPDX identifiers in composer.json.

At the moment the project lists: BSD-3-Clause, GPL-2.0, and GPL-3.0.
When running composer validate, Composer warns that GPL-2.0 and GPL-3.0 are deprecated SPDX identifiers and suggests using either the “only” or “or-later” variants:

- License "GPL-2.0" is a deprecated SPDX license identifier, use "GPL-2.0-only" or "GPL-2.0-or-later" instead
- License "GPL-3.0" is a deprecated SPDX license identifier, use "GPL-3.0-only" or "GPL-3.0-or-later" instead

Could you please confirm what the intended licensing is?

• Is the intention GPL-2.0-only + GPL-3.0-only (i.e., strictly GPL v2 and v3), or
• GPL-2.0-or-later + GPL-3.0-or-later (i.e., allowing later versions as well)?

For context, Nette’s 3.0.1 licensing has been clarified using the SPDX set BSD-3-Clause, GPL-2.0-only, and GPL-3.0-only, so I’m trying to align my understanding with the intended policy here.

Thanks in advance for the clarification.
