The rescuer does this to prevent symbol name clashes in other libraries.

In v5, just using the symbol name is no longer valid. Both the library
nickname and the symbol name are require. In the schematic file you
will see something like LIB_NAME:SYMBOL_NAME instead of just
SYMBOL_NAME. This will complicate the search/replace feature if we
decide to implement this. The problem becomes what do you replace, the
library nickname, the symbol name, or both?

These examples would only require changing the value field name not the
symbol used in the schematic which you can already do. Please keep in
mind that for symbols like transistors and logic gates there is a single
symbol with many aliases so your are not really using a different
symbol, you are using a different alias for that symbol. Aliases are
just a different name and information for the symbol graphical symbol.

The feature request would be "Change library symbol link name using
search and replace dialog."
