Best and Midi-sided recommend way is, if you insert
one MIDI Text Meta-event-Marker at the Start and one at End of your Map.
(within MIDI Editor).
-btw. for MIDI|Tempo-map..etc.pp, I really recommend to use at least 5.26pre7!!
Do it like this..

vs
embed..project tempo for consolidate/export/re-importing with DAW XYZ
"which would be naturally of course only embed the project tempo at the beginning of track/audio item xyz -into the Audio File(s) itself"
..)
BTW.
As easy readable example:
The above ASCII color Text show you the very well done exporting result from REAPER.
