In such a case, the file should not be included without an explicit
request from the user (or possibly via a package directly related to
it).

I don't know. I've looked at the problem more closely, and what
happens is that siunitx.sty does something equivalent to:
\AtBeginDocument {
\DeclareFontEncoding{TS1}{}{}
}
I can reproduce the problem with:
\documentclass{article}
\usepackage[utf8]{inputenc}
\DeclareUnicodeCharacter{00B1}{\ensuremath{\pm}}
\DeclareUnicodeCharacter{00B7}{\ensuremath{\cdot}}
\DeclareFontEncoding{TS1}{}{}
\begin{document}
Plus or minus: $±$ and ±.
Cdot: $·$ and ·.
\end{document}
\DeclareFontEncoding{TS1}{}{} has the effect to load
/usr/share/texlive/texmf-dist/tex/latex/base/ts1enc.dfu
because utf8.def (loaded by \usepackage[utf8]{inputenc}) modifies
\DeclareFontEncoding to do, in particular:
\InputIfFileExists{#1enc.dfu}
Is it normal that declaring a font encoding messes with the
input encoding? (I don't see how this could make sense when
the font encoding isn't even active like here.)
What is in cause?
