I respect your point of view, but until the RISC-V kernel port is more 
mature, I personally am not planning to merge this patch, for reasons 
discussed in the defconfig patch descriptions and the subsequent pull 
request threads.

I'm sure we'll revisit this in the future to realign with the defconfig 
debug settings for more mature architecture ports - but my guess is that 
we'll probably avoid creating debug_defconfigs, since only S390 does that.
