Using fields query parameter on showing a single resource

[aspyropoulos]

I want to query a single resource out of which I only need one field (title).
Is it a good practice to use the fields query parameter on showing a single resource? Is this a violation of the JSON API specification?
ie customers/1?fields[customers]=title

As far as I can tell its exactly what you want a fields parameter to do: https://jsonapi.org/format/#fetching-sparse-fieldsets
