HLS missing CODECS for H.265 streams

Description

When encoding media using ffmpeg for multiple HLS streams, the master playlist does not include the CODECS attribute for H.265 videos, but it does for H.264 videos. Here's a contrived command I'm running:

ffmpeg \
-i INPUT.mov \
-i INPUT.mov \
-i INPUT.mov \
-i INPUT.mov \
-s:v:0 1920x1080 -c:a:0 aac -b:a 192k -c:v:0 libx265 -b:v:0 4000k \
-s:v:1 1280x720 -c:a:1 aac -b:a 160k -c:v:1 libx265 -b:v:1 2000k \
-s:v:2 854x480 -c:a:2 aac -b:a 160k -c:v:2 libx264 -b:v:2 1000k \
-s:v:3 640x360 -c:a:3 aac -b:a 128k -c:v:3 libx264 -b:v:3 600k \
-map 0:a \
-map 0:v \
-map 1:a \
-map 1:v \
-map 2:a \
-map 2:v \
-map 3:a \
-map 3:v \
-var_stream_map "v:0,a:0 v:1,a:1 v:2,a:2 v:3,a:3" \
-threads 0 \
-f hls \
-movflags frag_keyframe \
-hls_flags single_file \
-hls_segment_type mpegts \
-hls_list_size 0 \
-hls_time 2 \
-hls_allow_cache 1 \
-master_pl_name index.m3u8 \
-y \
master_%v.m3u8

After the command runs successfully, index.m3u8 contains:

#EXTM3U
#EXT-X-VERSION:4
#EXT-X-STREAM-INF:BANDWIDTH=4540800,RESOLUTION=1920x1080
master_0.m3u8

#EXT-X-STREAM-INF:BANDWIDTH=2340800,RESOLUTION=1280x720
master_1.m3u8

#EXT-X-STREAM-INF:BANDWIDTH=1240800,RESOLUTION=854x480,CODECS="avc1.64001e,mp4a.40.2"
master_2.m3u8

#EXT-X-STREAM-INF:BANDWIDTH=800800,RESOLUTION=640x360,CODECS="avc1.64001e,mp4a.40.2"
master_3.m3u8

The H.264 streams have a CODECS attribute, but the H.265 streams do not. According to [Apple's documentation https://developer.apple.com/documentation/http_live_streaming/example_playlists_for_http_live_streaming/creating_a_master_playlist], the CODECS attribute is not required, but is recommended.

Since the logic for producing the attribute is already present for H.264 streams, could it be enabled for H.265 streams as well?

I've observed the current behavior with ffmpeg 4.3.1 under macOS Catalina 10.15.6 (19G2021).

This stems from issues I ran into some time ago. See comments in ticket:7480 and patch comment http://ffmpeg.org/pipermail/ffmpeg-devel/2018-October/235394.html for more details.

Essentially, one of the two reasons was that playback of HEVC content may fail even with properly constructed codec info while it works fine without it. The second was missing knowledge of proper syntax.

So this is the way FFmpeg handles it for the time being.
