actually you can, because the SwXParagraph instance is cached, so if
such an object already exists at the time when a new one is to be
created the existing one is reused.

in C++ you can compare that via just 2 css::uno::Reference<...> and
operator==, not sure how other UNO language bindings compare the object
identity, but it should be possible.

the only exception to this is if there is a paragraph enumeration that
partially selects a paragraph - those are never cached.

(also, not every UNO document  model service in Writer implements such
caching.)
