Can we do some sort of provider or so? Or hide initialization logic inside some class instead of doing it in REST service?

[benoitf]

@skabashnyuk I fixed the issue, what you're asking is a refactoring on how ProjectService was designed ? AFAIK these changes are handled by maintainers not by contributors.

@benoitf Can you elaborate on why the kind label is set to bug?

[benoitf]

@garagatyi you think it's an enhancement ?
For me it's a bug as creating an instance of an object should be always fast.

[garagatyi]

I do believe that marking everything as a bug is not convenient since it tempts ppl to mark everything as a bug to put up the priority and attention of other ppl in the project

[benoitf]

I've updated the label to enhancement if it's more convenient for people.
