It won't cause any harm!
If you're scripting (and also keyword testing), in my opinion, it's best to build up the name mappings that you will only interact with, first. Then organise your name mappings into aliases, so that you don't use long names when referring to an object, second.
The record feature, may end up creating duplicate name mappings, e.g. dropdownRegion, dropdownRegion1, dropdownRegion2 etc - depending on whether the parent object properties have changed (and name mappings haven't been defined first).
It's good to use the record feature to see how TC creates the script; you can use this to learn scripting, and use it as reference guide too.
Do what suits you best.
