@njacazio Why did you convert it to a draft?

[njacazio]

Hi @vkucera thank you for your PR. I moved it to draft as these files will be removed once they will no longer be needed for the ALICE 3 studies. The transition that will make them obsolete is not yet completed and even if they are not compiled for the CI these files are indeed actively needed and used as reference.
I will reopen the PR when it's the time to merge it so that we don't use CI resource on it. Many thanks!

[vkucera]

@njacazio OK, thanks for the clarification.

[github-actions]

This PR has not been updated in the last 30 days. Is it still needed? Unless further action is taken, it will be closed in 5 days.

@njacazio What is the status of the transition?
