guess that would work, unless a service implements 2 different
interfaces that overload the same method name (i hope we don't have any
such overloading...).

or you could call the method and catch the "AttributeError" if it does
not exist.

it's also possible to manually call queryInterface though probably that
is not idiomatic in Python:

pyuno object (com.sun.star.uno.XComponentContext)0x7f0941697060{,
supportedInterfaces={com.sun.star.uno.XComponentContext,com.sun.star.container.XNameContainer,com.sun.star.lang.XTypeProvider,com.sun.star.uno.XWeak,com.sun.star.lang.XComponent}}
