I am not convinced that multiformat runs of ngcc are more typical even on the command line.
Obviously the CLI will target only one property per entry-point.

But command line users who are not doing something similar (by providing a list of acceptable properties and asking to only build the first one) are probably wasting a lot of time processing formats that are not used.

But I think it is reasonable to keep one of the two (property or format) in the info message. But I found that keeping both just added a lot of noise to the message, making it less helpful.
