One comment about this situation.

I've fixed that issue by adding new key into

<type name="MSP\APIEnhancer\Api\CacheManagementInterface">
        <arguments>
            <!--
            This set of keys is for non-Varnish keys configuration
            It should be based on request information only
            -->
            <argument name="keys" xsi:type="array">
                <item name="store" xsi:type="object">MyCompany\WebApi\Model\CacheKeyProcessor\Store</item>
            </argument>
        </arguments>
    </type>

MyCompany\WebApi\Model\CacheKeyProcessor\Store returns new key with store Id.

Isn't the store code part of the URI

[rest/default/V1/products/:sku]

and with that a different key is generated?

I can't reproduce this issue...
