Step 1: Deploy VipsScaler extension, but only use it for PNGs over 12.5MP and/or TIFFs (which currently generate errors). Let this sit in production a while, fixing any bugs we find with this configuration.
I should note that PagedTiffHandler currently does support vips, but only unconditionally; we can't choose to only scale images with vips that are currently too large. If tiff support is to be enabled in the first step, then PagedTiffHandler should somehow be interfacing with VipsHandler, which does allow conditional scaling.
I think it's reasonable to include all of the TIFFs in the initial deployment, as a beta test. TIFFs are rarely used, and the people who upload them are relatively technically capable, so the impact of any issues would be limited.
