Pretty much every time I want to install a package I get a search for

  updating list of substitutes 

being on a slow internet line this sucks (not everyone has fast
internet! Think outside the US/Europe where internet is often still
metered on mobile lines), besides installing the same software often
install a host of new versions of dependencies. I don't like the
system changing under me - that is not a reproducible setup.

Q1: Do we retain older builds of binaries for some time for download?

Q2: Can we switch off updating list of substitutes? A command line
    switch would do. '--no-update-supstitutes'

Q3: Would it be possible to version the list of substitutes and use
    that for (re)deployment? That way I can truely regenerate an existing
    system.

Pj.

One curiosity appears:
which is your opinion about the Libreboot D16[1] ?
could be LibreFirmware an access to discover low-level SW creations for 
Guix?
