You are proposing to make it available with your proposed workflow,
where someone can download it.

Experience has shown that users will inconsistently simplify the data.
The best time to simplify is generally *before* converting to OSM
format, if using a format that supports topology.
If you must simplify a large number of ways in JOSM, first try giving it
more memory and launching with a console, and giving it tens of minutes
to complete. If that's still too much, only simplify a portion at a
time. Don't forget to adjust the simplify-way.max-error advanced
preference to be suitable for the data quality.
