Suggested package php-http/guzzle6-adapter is deprecated

[AngelinCalu]

The suggested package: php-http/guzzle6-adapter:

In order to use Guzzle v6 as the HTTP client

has been abandoned.

This package is abandoned and no longer maintained. The author suggests using the guzzlehttp/guzzle or php-http/guzzle7-adapter package instead.

php-http/guzzle6-adapter requires guzzlehttp/guzzle: ^6.0, however version 7^ is the major version adopted by most packages.

Is the suggested package still relevant for the latest versions of akeneo/api-php-client? I can see it was there in the suggestions since early beta.
