I performed distortion and TCA correction for my newest lens as promised. It is the Sigma 19mm F2,8 DN | Art in Sony E mount, it is also available in MFT. The script identifies it as "E 19mm F2.8".
It is the succesor of the almost identical Sigma 19mm f/2.8 EX DN which is already available.
See atached file.
I've been going through the lensfun 0.3.2 database file. It seems this lens is in there although only in MFT format. Maybe these entries can be combined?

Thank you very much! Which camera did you use?
Sony A6000.
I got some milk glass from the DIY store but will be on holidays first so I will do the vignetting corrections for both lenses (Sigma 30mm DC DN and 19mm DN A) in about 3 weeks or so.
Great! I included your data.
As promised I performed vignetting corrections for the lens. I used a milky plastic from the DIY store on a cloudy day. Judging by the corrected images it works very well :D
Attached is the lensfun XML file I currently use.
Okay, it is in! Thank you!
