I for one happily left tabulators behind.  But for make files.
The reason to use tab was file size for one, and that each editor
could be used interchangeably to work easily (backspace stepping
a real level, for example), and the reason for tab/8 was that the
files looked the same everywhere, on the printer, on the terminal
via cat(1), less(1), etc., so playing with vim(1)s tabstop
etc. setting was a fruitless dead-end.

On the 80 columns that i use, that i happily use, i just read
wireguard-tools source code (i am in the process of becoming
a hundred percent Wireguard fan, someone sat down and did
something really great i think) and even though it fits my screen,
it is just terrible to see lines that long (the kernel code fits
80, yay, not that i understand where all the work happens),
tabulators just cause crowding on the right, and then .. that
cannot be right.

Even though my coding style is easy not like that Linux kernel
code where function call arguments are then aligned under the
( +1, which ... no!  Well.  I switched to spaces when working for
free.  :)
But, not important.  A real change to my coding style came when
i looked around Plan9 source code, the pragmatism to simply not
use spaces in language constructs aka statements at all, for
example "if(a){" instead of "if(a) {" or "if (a) {", and let alone
"if (a)\nALIGN{\nALIGN" and whatever else.  I like that.  You
know, FreeBSD is thinking about using that clang format thing in
commit hooks (and maybe many even use the clangd "live" ctags),
and that was written in Acme or even Sam.  And the manuals were
great and the C dialect was, too.
