The erase operation on resume might be instantaneous with an SSD, whereas a rotary disk may have to write out several GiB for the same effect, at the precise moment you wanted to something useful with the device.

Although, it could be optimised by encrypting the data written out to disk and then only the key needs to be erased. Already that would improve the security/privacy situation, especially if hardware crypto were used, and maybe a 'reset' button to erase/change the key.
