Does anyone really say "SAYS" rather than "SEZ"?

The following extract from Grammarphobia (2008) seems to suggest that "says" pronounced /seiz/ can still be heard:

• Q: I hear BBC correspondents pronounce “says” with a long “a” to rhyme with “prays.” Why do Americans pronounce it like “sez” instead of like “pays,” “lays,” and other “ays” word that come to mind. Is it just a quirk of English?

• A: The third-person singular of the verb “say” should be pronounced “sez” on both sides of the Atlantic, according to American and British dictionaries. But pompous broadcasting twits, especially across the pond, have never let standard pronunciations get in the way of on-air affectations.

According to the following extract from Wise Words, /seiz/ used to be the standard pronunciation of "says" which was gradually replaced by the shorter /sɛz/. The former appears to have survived as a non-standard dialectal form:

• As the linguist Fidelholtz wrote back in 1975 — ‘Frequent words can do exceptional things’. The verb to 'say' is a good example of a mundane verb that is used a lot and that does exceptional things. ‘I say, you say, we say, they say’. There’s nothing peculiar here. It’s the so-called third person form that is the problem — this is where the verb falls out of kilter. In Standard English this is pronounced as ‘he/she/it sez’, and not ‘he/she/it says’. So it’s the shortened version ‘sez’ that is standard; the full form ‘says’ is now considered non-standard, dialectal.

• The pronunciation shift from ‘says’ to ‘sez’ must have occurred some time ago — writers were already commenting on it as far back as the mid 1600s. Frequency has to be the trigger for the change here. I can think of no other explanation. The ‘he/she/it’ forms of verbs are used more often than other forms. And so the repetition of ‘says’ will have the effect of streamlining the way we articulate it. In other words, we know what we’re doing; we’ve done it so often, so we make short-cuts.

• As in anything we do automatically, we get more efficient, faster and we decrease the size of whatever gestures are involved. In the case of speech, the transition between the sounds becomes more fluent — longer ‘says’ reduces to ‘sez’. You can see this also in the pronunciation of the form said, pronounced, in Standard English at least, with the same short vowel and not as you’d expect from the spelling (and as it was once pronounced) — ‘said’. Again you can imagine the regularity with which we produce phrases like ‘he said’/‘she said’/’it said’. Because we say it so often, we opt for a shorter route.
