This is the kind of thing that really annoy programmers (because in programming languages, you can never omit things like this), but everyone else is perfectly fine with.
I feel the same way, but I think programmers should hold their feelings and just pick up an APA, MLA or Chicago style guide or whatever the equivalent is if you're writing in British English and embrace the rules. Or if you're publishing, let an editor fix your stuff.
Every effort to make a logically consistent "engineered" language has so far failed by any reasonable measure, notably, Esperanto. Others have tried and had even less success than Esperanto. For things to even change in language usage there really has to be a pain point or some kind of trauma or isolation. Mere aspiration for aesthetics or logical consistency isn't enough. How did the American English come to be anyway? A bunch of people got on boats and went to a remote wild continent and stayed there. Forever.
My newspaper will shorten "United States" to "U.S.", and not add an extra period at the end of a sentence. (Not sure if the spaces are different widths.) When the next word would naturally start with a capital letter it can be difficult to tell whether the sentence ends after the abbreviation, sometimes making for garden-path sentences.

Though I am a programmer, so maybe it is just us...
In fact in some programming languages you can (or should) omit things like this. E.g. pascal does not require or explicitly forbids semicolon before end keyword.
Pascal is fully self-consistent here: in it, semicolon is a statement separator, not a statement terminator. Since the statement before "end" is the last one in the block, there's no statement to separate it from with a trailing semicolon, and so it's a syntax error.
In practice the separator-vs-terminator distinction mostly shows up in if-statements:
if foo then
bar
else
baz;
I believe that anywhere else in a statement context, you can put in as many extra ';' as you like and it won't make a difference. And of course you can drop the final ';' before 'end' or 'until'.
In those day when moving cursors with full screen editor (which is Not vi or Emacs), how many hours of my life wasted on this deletion of semicolons. Sigh.
Still I actually struggled each time this given not exactly sure I am in English or American camp.
As a programmer though, it certainly annoys me!
