Reducing WordPress archive weight

[sebastienserre]

Over the year, WordPress archives weight have increased and... I think we can't change this but we can surely do something on old feature which are no more used.
I know the backward compatibility is something really important to the WP leads eyes but we can't continue (IMO)to as 43% of the web to download files always heavier.
Maybe we could work with Core team to determine which functions are no more used and deprecated from years. Removing them will make WordPress liter.
I think to Classic editor, We could move all the classic editor features to the Classic Editor plugin. It would make the archive liter for the most part of the new users.
Features would be always available thanks to the plugin.
