I've got some Euro locks on external doors, but people keep locking
them and leaving the key on the inside. This means I can't put a key
fully in from the outside to unlock it.

Is this a bug or a feature?

Feature.

This can be changed by a locksmith in the more expensive cylinders,
i.e. Kaba, Keso etc.

It would have been better if those locks had been designed so you *can*
put a key in from the outside and open the door, while still leaving a
second key in the inside lock in case you need to exit in an
emergency. They could have a slide-latch which disables opening from
the outside if required for extra security when you know that everyone
who lives in the house is safely inside.

or just install one with a thumb turn on the inside

there's no need to have a key-lockable lock on the inside

If someone has broken in via a window, an easy=open door makes it far
easier to escape with his ill=gottten goods. Advice from our local Police
Crime Prevention Officer.

horses for courses

If there's only one permanent occupant of the house, then there's no
possibility of you leaving the key on the inside in the first place, so key
lock on the inside works

OTOH, if there's a possibility of someone being in the house when other
occupant is out, there MUST be a way of easily opening the door from the
inside in case of fire - either a thumb wheel or easily accessible key, so
ANO Burglar could use that as well

if you want 100% security when everyone is out of the house install a second
lock, only accessible from the outside

But that's a severe risk in the (unlikely) event you're mistaken about
the house being empty when you go out.

IMO one of the biggest common security risks in this country is letter
slots in the door.
