Why no lallans?

[Lallans]

At the risk of stirring the hornet's nest, Lallands is not a language but a a written form of the dialect from the Ayrshire/southwest area. It, that dialect, not spoken in my area or Aberdeenshire, Fife etc.

Britannica says Lallans is:

"Scots language (in Scots language (language))

"the historic language of the people of Lowland Scotland, and one closely related to English. The word Lallans, which was originated by the Scottish poet Robert Burns, is usually used for a literary variety of the language, especially that used by the writers of the mid-20th-century movement known as the Scottish Renaissance."

But whether or not you call it a language or a dialect or how regional it is and was is immaterial to the point I was trying to make. Am making.
