No, the re-target compensates so that the number of blocks in the last two
weeks is 2016. If a soft fork forces miners to throw away 25% of their
blocks, then the difficulty will drop by 75% to keep things balanced.
Throwing away 75% of blocks has the same effect on difficulty as destroying
75% of mining hardware.

The block interval will only increase until the next re-target.

Slowly increasing the fraction of blocks which are thrown away gives the
re-target algorithm time to adjust, so it is another advantage.

If the rule was instantly changed so that 95% of blocks were thrown away,
then there could be up to 40 weeks until the next retarget and that would
give 200 minute block times until the adjustment.
