Hello orson. I have nothing against people speaking in this way. It is not incomprehensible like some accents I have heard but it is not, on my opinion, a sound foundation for a crossword clue.
I see a similar point has been raised in another thread about the variation of homophones with locality. Like most Scots, too, I don't add a phantom r to the end of words like these.
I pronounce flaw as in "Aw, what a pity". Similarly caw (to resemble the sound of a crow), jaw, law, maw, paw, raw, saw.
Going through readers comments in other papers online, I quite often come across draw used instead of drawer and I wonder if the writer thinks that the word is actually draw but pronounced drawr.
