There is one good reason to come up with an agreement on this:
"An SQL server..."
"A SQL server..."
Both are valid depending on how you pronounce SQL. When reading about SQL one can generally tell how the author pronounces it through this usage. Jeff Atwood, for instance, always uses the second form in his blog posts as he prefers the "sequel" pronunciation.
Given that the ANSI organization has settled on ESS CUE ELL then in most technical literature the first form is used.
On forums such as StackOverflow, though, you'll find both forms, and in some cases it sparks an edit war between grammar, er, "enthusiasts."
Given that most written literature on the subject prefers the first form and agrees with ANSI, then when an edit war breaks out over something such as this, the conclusion should reflect the published standard.
