My understanding is, historically, the rex and senta have been shared machines where there is a chance devs can step on each others' toes.  I get the desire to have exclusive use of a machine but I don't want to have to be the one to police machine-hogging. Yeah I don’t think we want to lock them. Is there a specific reason people are asking?

If we want to do stuff that involves changing the machine state for more than adding new package dependencies, we should be working in containers or VMs...
