Your analogy appears to break down, and forgive me if my analysis is poor, when one considers the bandwidth.
Concerning oneself with HTML is different to fussing over optimising assembler in a regular computer because the mark-up is being pushed along many pipelines which are handling other data traffic, limiting the speed of data transfer limits processes involved in the presentation of the page.
I guess it's like optimising machine code to be run on a massively parallel computer in which real-time operation is desired.
In your analogy the compiler isn't [generally] producing the same assembly as if the code were hand-optimised. Clearly there's a play-off but if you could cut your transport across a data bus significantly with a couple of cheap and simple optimisations (either direct to the compiler or to it's output) then it's quite likely that you would, isn't it?
The main thing for me anyway was the surprise of finding this here. To add to my other poor analogy it's like going round to dinner at a famous chef's house and finding that they ordered the food in and just reheated it; just not what you expect. Sure you get a hot meal at the end of it, sure it might be nice, it's just you expected more.
