The alternative is trying to get one merged into the standard library. At least writing your own is better than not having one!

I often see this answer as a reason it's not particularly important to have on in a standard library.

I strongly disagree with that sentiment as often these simple things have subtle gotchas, and/or subtle differences in possible net effects creating much bigger problems than their diminutive implementations would suggest.

I generally feel the same way as you. My comment about getting it merged was not meant to imply that it shouldn't get merged, but that it might be difficult to. I find it very hard to predict which of these small QoL features will be accepted by the core devs and which features will be rejected for some reason or other.
