That's what I was saying. For people who are stuck to the holdover, it's just not useful to literally hit space twice if the goal is merely to increase the distance between the end of a sentence and the start of the next when the computer can do that for you.

It's literally the same argument between tabs vs spaces in code. The argument boils down to personal preference and taste of the amount of space. However, there is one truly valid argument that makes one more logical over the other: pressing a key multiple times to enter multiple characters to achieve a desired amount of space, instead of one key press and one character, is objectively bad.

If you simply prefer the stylistic difference, then you can change your settings to accommodate that. If you just don't want to do that, then do whatever you want. It's your prerogative to be lazy or whatever, and that's fine. Just like I don't care to add extra space after the end of a sentence because it doesn't bother me to have less.

However, anyone who teaches, preaches, or requires specifically adding extra key presses and extra characters is just plain wrong, because it's a stylistic preference. You can say that it's your preference to have more space, and you can say you don't care to change your settings so you don't have to press the key multiple times, but it is absolutely not objectively better in any way.
