there's always between 50 and 150 years of future data.
expanding to 2050 or 2100 is indeed not to far fetched to use as a general rule, but then you still have the "one max" (to) rule (them all).

IMHO it's actually not really relevant what the result is, as long as there is both an end and begin for the same year defined, even if it's outside the "end year" that is supposed.

so
OR  adding someting like 

> +Rule   Morocco   2038   only   -   Sep    30    3:00   0   -
> +Rule   Morocco   2038   only   -   Oct    30    2:00   1:00   S
> +Rule   Morocco   2038   max   -   Oct    lastSun 3:00   0   -

(or the equivalent of whatever "end year" is chosen) makes sense imho, even if the resulting data is "weird" or unlikely.
Or change
> Rule        Morocco        2026        max        -        Mar         lastSun 2:00        1:00        S
to
> Rule        Morocco        2026        2037        -        Mar         lastSun 2:00        1:00        S

It's quite possible those transitions will change 20 times the next 50 year anyway:)
