In general, I think this is a good idea.  Just from reading the
docstrings:

,----[ C-h v tex-start-commands RET ]
| tex-start-commands is a variable defined in ‘tex-mode.el’.
| 
| Its value is "\\nonstopmode\\input"
| 
| TeX commands to use when starting TeX.
| They are shell-quoted and precede the input file name, with a separating space.
| If nil, no commands are used.  See the documentation of ‘tex-command’.
`----

and

,----[ C-h v tex-start-options RET ]
| tex-start-options is a variable defined in ‘tex-mode.el’.
| 
| Its value is ""
| 
| TeX options to use when starting TeX.
| These immediately precede the commands in ‘tex-start-commands’
| and the input file name, with no separating space and are not shell-quoted.
| If nil, TeX runs with no options.  See the documentation of ‘tex-command’.
`----

You want to change the default values of the above, i.e., adding stuff
to `tex-start-options' and setting `tex-start-commands' to ""?

Does tex-mode.el process that information in any fashion?

From my experience, lualatex tends to be different from pdflatex here
and there, but not in this particular case.
