I agree. Subfolders/Subdirectories are a critical component in email service. On 2019/06/04 I asked Proton Support about this and here was their reply:
"Hello,
Unfortunately, the subfolder feature is not available to any subscription.
We are currently working on developing this and implementing it in one of our future updates."
Its good to know they are working on this long overdue issue, and hopefully it will get done soon. They must be losing a lot of money for the exact reason you described about not being able to switch or migrate other email account to Protonmail. I'm in the same situation and thousands of others may be as well. I'm sure there are many others that sign up for the free account, but won't become a paid subscriber because of this limitation.
