I do not think my intent was conveyed. Default aliases made by the product provider, regardless of who that is, are not a good path. If I was RCS, I would not make an alias that everyone had to take. Same for git. git has aliases, but they are for the user. If the end-user team wants to implement a particular set of primitives for their environment, that's fantastic, and entirely possible in git. But I do not want to be constrained by someone else's primitives that are not core product.

Then what is the point of this? I want my aliases, not someone else's. Again, if it is a core git alias, it is not an alias, it is a supported command and I should see it in the git help -a output.

The whole point is that a user team should give thought to the functional extensions they want, as a team, which is where aliases come in. We, as git contributors, should not be telling them what their extensions are.

Git is entirely bearable particularly in my own pons and medulla. I have three bash aliases, two for log, one for removing tags and no git aliases and I am highly productive.

Would that make ECLIPSE intolerable?

I remain unconvinced and I found the assertion #5 somewhat specious and incorrect. SCCS and RCS use Shell aliases. There are no aliases in ClearCase. Granted Perforce has them, but that is not a sufficient differentiator to use that over git by any stretch.

Why are we trying to create a standard set of aliases? I do not like the RCS primitives - never did - as a base and would not use them. If the command set is not sufficient, then it should be extended. If it is sufficient but complex for some, *they* can create aliases. I come back to my point that a community-based set of alias extensions should be managed as a distinct Open Source product that can be cloned from some cloud service and maintained independently from git. There is nothing stopping that from happening, except perhaps for something like an include operation in .gitconfig, which I think would be either a really good idea, or subject to a CVE, or both.

I've expressed my opinion, and it's not my decision to adopt this. So whatever happens, as long as it does not pollute my community's expectation of git. Although, providing aliases will handcuff future command naming.
