There is a small extra cognitive shift where the brain realizes those aren’t typos or random letters and are intended to represent those words, so it does add an impediment to understanding. If it became common for people to write them as ‘r’ and ‘u’ then over time that would become correct.
Just like if it was common for people to pronounce “gif” one way and then someone came along and said “Well the creator wants it pronounced another way” the correct response is “who gives a fuck? This is how the word is used now.” The ‘creator’ of the word “island” did not have an ‘s’ in it, but no one is arguing for it to be spelled “eyland”.
You re-read sentences much more often than you might suspect and it happens with all kinds of sentences, even grammatically correct ones. Garden-path sentences, for example “the old men the boat”, are specifically crafted to demonstrate this and they essentially are doing the same thing as using ‘r’ and ‘u’ as a substitute for words: they violate the Gricean maxim of manner and that one relies a lot on expectation.
However, one could make a case that in some situations, like a “how r u” via text, the replacement is ubiquitous and somewhat expected and doesn’t cause any impediment to understanding. It’s definitely a hinderance when a more verbose communication is expected. Might be a neat subject for a phonetic study, honestly.
