Except that the current wording of the TGPPL s1.c proviso doesn't
match what you are describing.
Under the TGPPL as it is, you could distribute copies of the source of
your derivative work under another license than the TGPPL, as long as
that other license terminates within the 12 months period and is
replaced by the TGPPL. I guess regarding the code that would be
covered under the copyright of the original work, that other license
would be the one granted to you by s1.c. The proviso itself becomes
the license for that initial period during which the TGPPL is suspended.
Instead of allowing the suspension of the entire TGPPL license, s1.c
should have been worded in a way that would only suspend the
requirement to provide source.
