4 months ago I agree with your opinion. I will remove the option in the next release.
Let me explain why I added the option for my future notes. As of time of writing the code, I refered to the 303's GoldSrc Spraylogo Tutorial as the one of the reference about Goldsrc spray format. It says "Valid sizes ONLY for Sven Co-op using manual .wad creation in wally.exe (maximum surface 14436)". However, as @sappykun posted it, large size spray can be used in Half-Life and its mods.
I could use your spray with the newer build of Goldsrc (25th anniversary update) as you did. I tested it on the vanilla Half-Life, Half-Life: Before, which is available on Steam and Scientist Slaughterhouse, which is available on RSTL. The spray could be used on all of them.
Anyway, thank you for your report.
The surface area check for Goldsrc sprays appears to be unnecessary. I am able to load sprays with a surface area of 14336 in other Goldsrc titles such as Counter-Strike 1.6 (at least in Goldsrc builds 9920 (current) and 8284 (legacy), I haven't checked with anything earlier than that), so the toggle should be removed and the surface size should always be set to 14336.
For example, here is a spray I have made (in PNG format) with dimensions 112x128:
tempdecal.zip
and here it is in Counter Strike:
I believe this misconception started since HLTagConverter wasn't able to process images larger than 12288 for some reason, so everyone assumed that was the maximum size. A very similar thing happened with Source engine sprays, where everyone assumed spray dimensions had to be a multiple of 2 because VTFEdit insisted on it when you imported images (it was trying to create mipmaps for textures, which DO require 2^n dimensions, but DXT textures only need to have their dimensions be a multiple of 4 if you have exactly one mipmap).
