@mengqiy can these flags be fully removed for both v2 and v3 projects or just v3?

[camilamacedo86]

Hi @estroz,

V1,V2,V3 are versions related to the project scaffolded layouts and not cli-tool.I mean, to allow breaking changes in the scaffolded projects we need bump a new project/config version.

However, since we will bump an upper version for the next release (3.0.0) then, I understand that we can move forward and remove the args which are deprecated a while for v2 and v3.

@mengqiy please let me know if I misunderstand something here.

@camilamacedo86 fair point, although we can control what different project versions see in their CLI. I just wasn’t sure whether dep flags were deprecated alongside or independent of v1 deprecation.
