but you didn't add anything to support that claim

Oh dear. Come back in the morning when you've calmed down. And if you still cannot see the evidence I posted, go get your eyes tested.

You've showed that Deparse considers for (;;) {} and while (1) {} equivalent (which means there's a strong chance that they are very similar). This is consistent with while (1) {} getting optimised to for (;;) {}, so it doesn't support your contradiction.

You've showed that Deparse considers while (1) {} to be more readable than for (;;) {} on average. This doesn't support your contradiction.

So you didn't show that while (1) {} doesn't get optimised to for (;;) {}. Easy to prove that it does, though. Note the lack of any condition in the following:

>perl -MO=Concise,-exec -e"while (1) {}"
1  <0> enter
2  <;> nextstate(main 3 -e:1) v:{
3  <{> enterloop(next->5 last->6 redo->4) v
4  <0> stub v
5  <0> unstack v
-e syntax OK

For comparison,

>perl -MO=Concise,-exec -e"for (;;) {}"
1  <0> enter
2  <;> nextstate(main 3 -e:1) v:{
3  <{> enterloop(next->5 last->6 redo->4) v
4  <0> stub v
5  <0> unstack v
-e syntax OK

Not to interrupt our regularly scheduled disharmonious bisecting of the rabbit, but perhaps while(1) gets optimized to while():

 % perl -MO=Deparse -e"while() { print }"
while (1) {
    print $_;
}
-e syntax OK
 % diff <(perl -MO=Concise -e'while($x){print}') \
        <(perl -MO=Concise -e'for(;$x;){print}')
 %

Carry on. (Like I could stop either of you.)

Gah! You really are infuriating when you go into your pointless, my-view-of-the-world-is-the-only-view defensive mode.

But you didn't show that while (1) {} doesn't get optimised to for (;;) {}. Easy to prove that it does, though. Note the lack of any condition in the following: ... For comparison.

So, the way you choose to view this is that for(;;) {} gets parsed as while(1){} (as demonstrated); but then, because the generated condition is a constant, it get "optimised" back to a special form of for again.

That couldn't possibly be simply an unconditional loop.

You really do live in a world of your own making don't you. (I'm done.)
