You obviously misunderstood me. I do not support Calabria's policy of keeping the GSEs small with excessive capital requirements. However, I think what he has written in his book is eye-opening. It gives a sense of what ideas and strategies the secretive top people in the Trump administration, including Mnuchin, really had regarding recap/release.
Even if someone other than Calabria becomes FHFA director in a second Trump administration (which is very likely), it is safe to assume that what Catman wrote in his book will continue to reflect the prevailing policies and (behind closed doors) ideas. It is a look at the past, but also a look at the future.
