The only actual change here is that if you don't recertify when a new product is out, you'll lose the right to claim to be VCP. That said, most places I've been, saying you're a "VCP" is immediately followed up by "VCPx?" with x being the current VMware major version.
And since VMware for years have offered a grace period where existing VCPs can upgrade their VCP cert by taking the exam without a course within a few months of the new version being available, I don't see this as a big change.
I took both my VCP4 and VCP5 exams without courses after taking the mandatory course just for my VCP3 exam.
