The initial crashkernel size is just a default value - that was in the
past a reasonable good value.
So it's not uncommon that one needs to increase the crashkernel size for a
particular situation and setup.
The default size is always a trade-off between reserving enough space for all
possible situations and environments vs. not reserving and wasting too much
space.
But we already noticed that the default needs an increase nowadays,
which was in general already addressed in LP#1877533. LP#1877533 is not
done yet, since the approach is to do it in alignment with Debian.
Nevertheless, I tend to mark this LP#1946463 as duplicate of LP#1877533
