How would this pod impact the Haldane reforms?
Those were learning's from the Boer war that made a serious difference to Britain's ability to raise a Continental force through the very sensible reorganisation of the then OTL eclectic 'reserve' organisations.

One outcome was the discovery of level of unfitness and malnourishment shown in those of the working class volunteering at Army recruiting centres.
Political butterflies: -
No "methods of barbarism" speech, which really cemented Campbell-Bannerman as Liberal leader.
David Lloyd George doesn't grab the public spotlight with his speech in Birmingham where he nearly got lynched; no "Chinese slavery" speech in the Commons either.
The Education Act of 1902 is more successful; Sir Robert Morant informed Joseph Chamberlain that "your war" prevented rolling it out to cover voluntary schools - now there would be the budget to achieve that.
Tariff reform - does the political & financial background obviate the need for Chamberlain's campaign that split the Unionist Party?
No landslide general election victory for the Liberals. Do the Unionists hold on?
