Re: TOS Enterprise - function of warp nacelles' caps?
"Even the example of "James R Kirk" can be attributed to a fallible and human god Gary Mitchell vs a retcon."
I read somewhere the "R" stood for "Rice" and was a nickname for Kirk at the Academy.
Considering the tombstone dates might just be the stardates to indicate Kirk's short career as captain, it would just be another evil farewell joke at the expense of Kirk.
