@Adair M in no way am I second guessing you, nor discounting that.
I have to inject my experience with my cascade where I lost this entire year to recovery.
In Fall of 2017 I thinned the foliage, in the Spring, though a bit early I repotted it into a larger
grow box I made for cascade. I was scoffed for setting the style up to go wild ruining the current style
giving it more room to grow. Instead, potting up at 1st sign of growth as we do with pines
I repotted. I slowed the growth of that procumbens immensely to the point of concern and worry.
By Summer only concerned, to this day I have not pruned on this juniper.
I wished I had left it more unruly and thinned it after recovery this Fall rather than the Fall prior to potting.
Here is the shimpaku for this pot.

A Fall repotting was considered, but we travelled and a black fungus like growth is atop
the roots of a couple trees on the nebari and even this juniper has some black on the bark.
I can't fix stupid with an unwilling to learn or care family member who has their own ideas
on how to water. Anyway, for the Fall consideration all foliage was left unchecked.
I will remove more lower growing foliage, and do you think I should remove all the new growth tips too
considering that I like to keep it unruly prior to a Spring repot this Fall and rely on the new growth tips
come Spring to aid in recovery? These current growth tips (where energy is derived from) will be replaced
come Spring with new ones I know, but I still have to ask if these ones today, can help increase vigour
after repotting next May late April maybe? Having never potted this one up, and the amount of expected
root reduction, I want all props I can get for this fella.

Here's the cascade, and the only plump growth tips are on the lower apex.
The rest is active, but to a much lesser degree, to the point that it is stymied.
