Your plant is incredible! No wonder it's blooming, so gorgeous and healthy looking.
Removing the bloom is one of those seemingly vindictive advices that may originate from jealous folks whose plants won't bloom. If you were putting all of your focus into making a bloom and it was suddenly cut off, would you suddenly "grow faster?" The most logical response to me seems like it would be confusion. I don't know how plants process this, but why not enjoy a bloom?
There may be some element of the advice that comes from confusing annual plants with perennial plants, combined with a theory that removing the bloom of a true annual plant can lengthen the life of that plant, but one would have to first believe that an annual can be so manipulated to believe that removing the bloom could have that effect. Regardless, none of that relates to perennial plants because their health is not compromised by blooming, it's just what they do when they are mature, robust and healthy, in conditions that allow it to happen.
There can be technical reasons why a bloom of some plants are removed, but they are in regard to manipulating the plant, not in regard to "healthcare."
