Hi,
Reducing precision could lead to corrupted data with WFS-T. Perhaps server
should accept the parameter, if it comes true, only when it is not configured
to support transactions.

Aihe: Re: [Geoserver-users] Reduce precision of WFS output to decrease response
size?
Well, isn't this the Discussion phase of the feature request?
And as I mentioned, although it would be great to see this done, unfortunately
we may not be able to make a good case to fund it.

Here's another reason why reducing precision of responses on-the-fly would be
useful. It turn out the data as stored in EPGS:3005 essentially has 1 m
precision. However, we are requesting it reprojected to EPSG:3857. The
reprojection creates values using full double precision, which is output by
GeoServer. So in this case it is perfectly safe to round back to 1 m precision.
We will explore requesting the data in the native CRS, since we can project on
the client-side. But it would be nice to be able to do this fully in GeoServer.
By now you should know that just being right about the usefulness of a feature
request achieves.... exactly nothing ;-)
