Default remappings_version to false

[marktoda]

IMO the remappings version should be defaulted to false. It's quite annoying to have to update every import location on upgrading version, and benefit is unclear to me

Similarly why not make recursive_deps default to true and remappings_regenerate default to true?

IMO defaults should cover the average/basic case, and custom configs for power users who want more complex behavior. I feel that auto-generating simple mappings is the most likely case

The next version (0.4.0) will default to include a version requirements string in the remapping name, as opposed to an exact version. As such, you will be able to specify @openzeppelin-contracts~5 and that will be the default remapped path (@openzeppelin-contracts-5/=dependencies/...). This means that you will then be able to keep the same imports as long as you don't switch to the v6 of this package. You can even be more granular like @openzeppelin-contracts~^5.0.2. Updates will not affect your existing remappings (the left part of the equal) as long as no major version change has occurred (which must then be updated manually by changing the config file or using the soldeer install command again with a new version specifier).

To expand on this, it's important to include some kind of version info in the remapped path so that if one of your dependencies uses a different major version (e.g. openzeppelin contracts v4.x), both package versions can co-exist and use a different import path to avoid resolution conflicts.

For remappings_regenerate, we want to keep it default to false because that means users can easily customize their remappings without them being overwritten, so it makes sense to be the default. It should have no impact on users who do not customize remappings.

Regarding the recursive install, I think we might consider a change in defaults once we are sure it matches the use-case of everyone and there are no major drawbacks to using it.

Hey @marktoda , is my answer satisfactory or do you still think the default should change? Please also check this section of the new usage guide for an explanation.
