Not that I mind being at odds with a generally-accepted framework.

It is my understanding (I just read up on this
)that "common descent" refers to the source of all existing life, and not to alternative life architectures. If these alternatives were entirely incompatible with our current system, then extinction would leave little or no fingerprints.
OK, it is thin, but not impossible
I suspect that my hypothesis will remain just that, unless some caches of alternate life are found somewhere on this planet feeding on an as yet unknown energy source.
Bio, I would bet you rather like being at odds with the generally-accepted framework when you can justify it
