Not really, each pet is unique and the Mu Guardian is the only one that heals; Soul Mastery has a Seer pet which gives you +Per and Confuse resistance. This change just makes Mu Mastery even more compelling choice if you're going to take the patron powers, mostly because of Charged Armour and Power Sink.

This is great.
I can see the good things in Mu and Seer, but seriously, the other two pets, do they have anything going for them? I guess the slow cone from the coralax could be considered a selling point, as could the -fly the bot is spamming, but they seem awfully weak compared to the other two.
Other than that, damn the Guardian seems a nice choise

The Toxic Tarantula does purely Toxic damage (clue is in the name 
) with DoT ticks from range and melee, and I'm pretty sure the melee damage it does is fairly hefty. It's also pretty resilient, as well as spewing the -Fly Web. I think the Coralax has a couple of cone attacks as well as the Shiver-esque cone - not massively useful, but could provide either some synergy with certain sets.

Just out of interest, what would happen if someone did powerboost and then summoned the pet? No effect I'm guessing, but just curious.
Apologies if I'm out of date on this - I've noticed the Mu Guardian patron pet has changed in that you can now slot it for heal.
On my level 50 Dominator this means a heal of 417 with 3 slots of heal SOs, which is about 40% of my total health. To compare, Aid Self is 389 also with 3 slots. According to nofuture.org the heal (Touch of the Storm) has a recharge of 20 seconds.
This means it's twice as powerful as it was previously as a healer, now I'd be tempted to slot it for 3/3 recharge/heal. Which would give it an uptime of 4 minutes, downtime of a minute and a half.
