I didn't know about the MH10 Data Identifier, Harald, thanks.
As far as I can remember, I based it on finding real world examples on the net. One example was at https://www.vinquery.com/vinbarcode, the 3rd Canadian image "vinbarcode4.jpg" - if you scan that you'll see it has a hidden "I" prefix. I do recall finding a good number of other examples at the time.
My feeling is that it's an American manufacturers' thing (perhaps used in their plants abroad), nothing official. Although the VIN number itself is well regulated, the barcode as far as I know isn't.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
What I observe in Industry is, that the people having installed this in the 90th are retired and nobody remembers any more the intention.
I suppose, AIAG has a document and a decision on this, and ODETTE or JAIF may also, but those documents are out of sight of todays ingeniers equipped with an iPhone view of the world.
Take care,
Harald

Maybe, the following information is related:
The "I" is the "Data Indentifier" for a VIN Code following ISO/IEC 15418.

Googling now I find https://github.com/mikebuss/MTBBarcodeScanner/issues/27, which has some more links in the comments. Also https://www.dynamsoft.com/blog/imaging/barcode/scanning-vin-codes-barcode-reader/.
