I kinda concur with this statement. You just simply canāt have too much Z1/Z2 in your training and commuting is a great way to get some more in. That said, I like to push it every once in a while on the commute (i.e. if Iām running a touch late, or I want to attack a hill, or just felling like it).
What I did to balance things out and keep track of my load, I invested in an armband-style HRM and committed to wearing for all commutes. I have both a Polar model and Scosche model. They are both good. Why the arm-band? Sealed, rechargeable and you can slide it on at the last minute no matter what clothes you are wearing! No disrobing fro the chest strap HRM.
Alas, getting outside date into SYSTM is not a thing, so I have linked my Strava to intervals.icu and track my training load there. Or, if you have a paid Strava account, you can use their " Fitness & Freshness" page, but intervals.icu is better IMHO. At the moment, I just use a non-paid account there, but I would like to throw them some money. I wish they would just take tips.
By tracking my training load there, I use the Form section of the Fitness graph to know if I am Fresh, or if I am in the High-risk realm. If Iām in the red or approaching it, I will move hard workouts around until I am out of the red.
Hereās my graph for the last 6 monthsā¦ try to spot when I broke my collarbone. Ha!

And hereās a section when I was doing a really good job of keeping it in the Optimal or Green zone. Try to spot when I met my new girlfriend.

EDIT - I hope to be cleared to ride outdoors again after a doctor visit tomorrow, which will hopefully get me back on the commuter and more!
EDIT 2 - I have also been walking a lot since the collarbone break (to get some outdoors time) and I am recording those via Apple Watch so that training load gets into my data as well. If I was riding like I normally do, I would not typically bother to record a walk unless it was a significant hike or similar.
