Do you know how long this takes? Most probably it will take years to change.

That seems reasonable.

Tends to take years to develop new connectors, and longer still to develop new objectively better connectors.

The USB-C specification is 8.5 years old at this point, and we will have another year before this mandate takes effect.

Hopefully future EU mandates can optimize that near-decade timespan from standardization to being legally allowed by hardware manufacturers.
