[TR] Silicon brake fluid

I Know, I know, this topic has been beat to death several times over the
years, but I have a very specific question.

I yesterday received a brand new early Spitfire brake dual master cylinder.
It is manufactured by TRW and has Lucas cast into the body.  On the OEM
box there is a warning Use of Silicon brake fluid will void warranty.

I have used silicon for several years in my rebuilt TR3 cylinders with no
apparent adverse effects and generally have been pleased.

Does anyone have any long-term experience using silicon in a Spitfire
master?  My guess is that is a liability issue and the manufacturer is being
overly cautious by warning against the use of silicon, but I am very curious
as to any real world observations in this regard and any educated guesses
as to why TRW would put such a warning on their label.

TIA
