Support of desc and cmt of gpx files

I am using Garmin Explore for a couple of month and I want to migrate my data using gpx import.

Unfortunately, Garmin Explore seems to ignore some of the default gpx standards such as <cmt> (comment) or <desc> (description).

I.e.

<?xml version="1.0" encoding="UTF-8" ?>
<gpx xmlns="http://www.topografix.com/GPX/1/1" creator="" version="1.1" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.topografix.com/GPX/1/1 http://www.topografix.com/GPX/1/1/gpx.xsd">
  <wpt lat="37.754007" lon="-122.447175">
    <time>2008-04-10T22:28:07Z</time>
    <name>this is the name of the waypoint</name>
    <cmt>this is the comment</cmt>
    <desc>this is some further description</desc>
  </wpt>
</gpx>

Furthermore: if I save some comments to a waypoint inside of Garmin Explore and do an export, the comments are not exported.

I. e.

<?xml version="1.0" encoding="utf-8"?>
<gpx creator="Garmin Explore App" version="1.1" xmlns:adv="http://www.garmin.com/xmlschemas/AdventuresExtensions/v1" xmlns:gpxtpx="http://www.garmin.com/xmlschemas/TrackPointExtension/v1" xmlns:gpxtrx="http://www.garmin.com/xmlschemas/GpxExtensions/v3" xmlns:gpxx="http://www.garmin.com/xmlschemas/GpxExtensions/v3" xmlns:trp="http://www.garmin.com/xmlschemas/TripExtensions/v1" xmlns:wptx1="http://www.garmin.com/xmlschemas/WaypointExtension/v1" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.topografix.com/GPX/1/1" xsi:schemaLocation="http://www.topografix.com/GPX/1/1 http://www.topografix.com/GPX/1/1/gpx.xsd http://www.garmin.com/xmlschemas/WaypointExtension/v1 http://www8.garmin.com/xmlschemas/WaypointExtensionv1.xsd http://www.garmin.com/xmlschemas/TrackPointExtension/v1 http://www.garmin.com/xmlschemas/TrackPointExtensionv1.xsd http://www.garmin.com/xmlschemas/GpxExtensions/v3 http://www8.garmin.com/xmlschemas/GpxExtensionsv3.xsd http://www.garmin.com/xmlschemas/ActivityExtension/v1 http://www8.garmin.com/xmlschemas/ActivityExtensionv1.xsd http://www.garmin.com/xmlschemas/AdventuresExtensions/v1 http://www8.garmin.com/xmlschemas/AdventuresExtensionv1.xsd http://www.garmin.com/xmlschemas/PressureExtension/v1 http://www.garmin.com/xmlschemas/PressureExtensionv1.xsd">
	<metadata>
		<name>Ehrbachklamm</name>
		<link href="http://www.garmin.com">
			<text>Garmin International</text>
		</link>
		<time>2022-05-29T10:26:17Z</time>
	</metadata>
	<wpt lat="50.190564" lon="7.465851">
		<time>2022-05-25T08:49:14Z</time>

	</wpt>
</gpx>

As you can see in the second code snippet, the gpx file even supports the schema https://www.topografix.com/GPX/1/1/gpx.xsd which includes desc and cmt elements.

My question/suggestion is: if I can save comments to my waypoints in Garmin Explore already, why not using the standards? 

Use case why I use comments and description at all: comments and descriptions are kind of a log book for me where I store experiences I made on a trail/at a waypoint.
