Every iOS app is currently tested in x86 on the Mac simulator and then ARM on the device.
If you ship a Catalyst app that runs on iPad and Mac you are shipping and testing on x86 and ARM.
Apple already splits binaries in the app store and only downloads what is needed for your device (including resources for different device resolutions), so the end user would likely not see an increase in app size.
