One way to go here is to add another check in the DRC:

X Is the schematic design in sync with the libraries?

giving you a list of symbols (may be empty) that isn't in sync.

Then I could by my self decide if I should upgrade some or all symbols that
gives a warning or not.

in the library, you don't necessarily want to automatically update all of the
instances of the older version of the symbol. I would be much more concerned if
after updating all instances of older definitions of the symbol, the now unused
definitions stuck around in the design file with no actual instances being used.

Another user suggested that we add the ability from the symbol editor to push
the newer version of the symbol out to all instances in any open designs - I
would find that a very desireable ability also - but only upon a manual command.
Otherwise, you could risk losing important design info if all symbols were
always automatically updated, potentially also causing symbols to become
disconnected if origins or pin lengths were changed.

As a result, sometimes pins get disconnected from wires, especially when I
copy/paste schematic to a different file.
