A problem with all English spelling reform is that it is often intended to be phonetic and usually favours the pronunciation of the person proposing the change another is that it makes homophones also homonyms.
Where I come from in the South West of England bath has a long a and so does castle but in the North East they both have short a. Which one should the orthography reflect? What about house? Pronounced almost to rhyme with mice in some quarters and moose in others.
What do you do about Shrewsbury when even the locals don't all agree on how it is pronounced? Will Scots get to spell the name of a large aquatic mammal as hwale to more closely match the pronunciation? One positive change might be that in England the word wales would be reserved for the animals and we would all start referring to the country as Cymru.
If spelling reformers want to spell words differently then they should just do it the way that English has done for centuries, just do it. If you prefer to write labor rather than labour then do so. If you would rather write jeeny than genie go ahead. After all as mentioned in the article there is no English Academy to tell you not to. If others agree then the written language will adjust.
My Norwegian teacher was adamant that Norwegian is pronounced as written despite knowing perfectly well that almost every valley here has a different accent or even dialect. Norway gets away with it only by declaring that the two official forms are merely standardised written Norwegian; no one actually speaks bokmål or nynorsk.
Shouldn't it be laybuh, anyway?
It's pretty normal to have a somewhat deficient but still mostly phonetic script. So you _can_ read it purely phonetically, but you would sound robotic and/or unnatural. It also might miss some information that is obvious to native speakers.
Most Slavic languages belong to that category. E.g. Russian and Ukrainian texts usually don't mark the stressed syllables. Russian tends to reduce vowels so they are pronounced ambiguously. Czech had some vowel shifts so that some letters are now pronounced identically, etc.
It's still much better than English, where you often need to _know_ how a word is pronounced (e.g. "put" but "putty").
The article’s example of “mis(c)e(l)lany” is one example that stood out to me like this - perhaps in some dialects it’s pronounced with a single S sound, but it’s definitely two for me. (And on the flip side, I wouldn’t retain the second I in “suficient”.)
