Upon further thought, it appears the search warrant itself does not grant the authority to compel other parties -- whether involved or not -- to labor in the execution of that warrant. Rather it is the application of the 1789 All Writs Act...
Yes, I assumed that was what you meant: the warrant allows the search and the All Writs Act provides for court orders in support of the warrant/search.
...which was used to command third parties’ assistance to execute a prior order of the court.
It was? Can you give an example of where the All Writs Act was used to command a third party's assistance? Also, if that is already true, I'm not sure what your point here is then, since the question would be already answered and therefore moot...
Also the issue exists whether you define it as two parties, three or more. E.g, what if the government felt that Google with their vast technical resources and prior competitive reverse-engineering study of iPhones could construct hardware/software to weaken iPhone encryption. Could Google be compelled under the All Writs Act to render this service?
Still no.
In this case it would seem limited by the Communications Assistance for Law Enforcement Act, which states that law enforcement cannot "
require any specific design of equipment, facilities, services, features, or system configurations".

As far as I can tell, those words do not appear in that wiki article. Where did you get them? It does say, though:
"CALEA's purpose is to enhance the ability of law enforcement agencies to conduct
electronic surveillance by requiring that telecommunications carriers and manufacturers of telecommunications equipment modify and design their equipment, facilities, and services to ensure that they have built-in surveillance capabilities, allowing federal agencies to wiretap any telephone traffic; it has since been extended to cover broadband Internet and VoIP traffic."
It appears to me to say exactly the opposite of what you claimed. Can you show me where your quote came from or otherwise explain this discrepancy?
Also, that law wasn't part of the current line of discussion, unless you are saying that it adds/clarifies power to the All Writs Act. In either case, I do think most observers agree at this point that it would be best for that law to be updated to include (or explicitly exclude) the current situation.
