Is that a rationale, or an irrationale?
According to 'ps', an all-up ssh system is less than 3 megabytes (sshd, ssh-agent, and the ssh client). At current memory prices, your clients would save less than $1.50 per system even if their custom software could reduce this "bulk" to zero.
Without commenting on the general merits or otherwise, $1.50 is a big deal if the
target product is some embedded device intended to sell for $10 to $20 and/or if
the target product is part of a system in which millions of such devices are intended
to be used.
