Changing the user-visible API is a hard egg to swallow, and it's unfortunate that the Python code used a dict to hold "flags" to begin with. The dict doesn't just record whether an exception has occurred, it also counts how many times the exception occurred. It's possible that someone, somewhere, has latched on to that as "a feature".

Especially since it was a documented one:

import decimal help(decimal.Context) Help on class Context in module decimal:

class Context(builtin.object) | Contains the context for a Decimal instance. [...] | flags - When an exception is caused, flags[exception] is incremented. | (Whether or not the trap_enabler is set) | Should be reset by user of Decimal instance. [...]
