The RPi 3 based hardware has several limitations, which we work around using various tactics. For example,
mimic2 is currently cloud-based (for both RPi 3 hardware and Linux installations), but it’s possible it could be on-device for Mark 2 - there’s no way we could make it in-device for RPi 3 due to the compute requirements.
We also work around other quirks on RPi 3 hardware - for instance the setup menu is used to help detect audio devices, and you need to manually edit
wpasupplicant.conf for wireless access - because the software we used previously for this on Mark 1 (which is based on Raspbian Jessie Lite) is not longer supported on Raspbian Jessie Stretch - which is what Picroft is now based on.
So the summary here is “it will be harder to do on-device capabilities that require compute, these will likely be moved to cloud services”, but other functionality is likely to continue to work.
